Decommission Lync 2010

Hi
I have just upgraded a Lync 2010 Standard system to 2013. The cms is moved to 2013 and I have uninstalled cms on the 2010 server. The users and conference data is moved to 2013. Therefore, my last step is to decommission the 2010. Before
I procedure with this in the Topology, I notice two things. 1. When I use the command Get-CsSite the old 2010 shows as register and so on. But if I use Get-CsService the new 2013 is primary and in Topology all points to new cms in site. Howe come Get-CsSite
point to 2010? The other thing is when I open up Control Panel the old and new URL is given. Does the URL disappear when 2010 removed in Topology?
Best Regard
Daniel

Hi,
The Lync Server Management Shell Get-CsSite retrieves information for all the Lync Server sites. It should show all the sites information and the pool, services. Make sure all Edge Sever and PSTN Gateway point to the new Lync Sever 2013 Pool.
During the co-existence environment, it will show both Lync Server 2010 and 2013 URL to access Lync Server Control Panel, after delete the Lync Server 2010 pool from topology, the Lync Server 2010 URL will disappear.

Ready to decommission our only Lync 2010 FE server

We are fully functional on Lync 2013 including our Edge server. I have a single Lync 2010 FE server I wish to remove. There are of course no users on it. We never used conferencing and no telephony at all. Just simple IM and presence. The 2010 server was
more of a proof of concept and just had our IT department as users.
The CMS was moved to 2013 a long time ago and I am at this point ready to remove the 2010 server completely. There are so many articles out there with way more detail than I need. I am thinking the steps are just this:
Verify no users, contacts devices etc... exist on the 2010 server
Delete the Conference directory on the 2010 server (No data because we never used conferencing)
Uninstall the CMS from the 2010 FE using the PS command
Uninstall-CsDatabase
-CentralManagementDatabase -SqlServerFqdn <FQDN of SQL Server>
-SqlInstanceName <Name of source server>
Remove the 2010 FE from Topology builder answering yes to removing the file share
Publish the Topology
Run setup.exe on the Lync 2010 to remove components (not sure about this step)
Done
I tried following some of the many documents out there but many don't mention the uninstall of the CMS on the legacy 2010 server and the MS documents go into exhaustive detail, much of which doesn't apply to me.
Lastly, I noticed in Topology builder there is the Lync 2010 SE FE server, an A/V Conferencing Pool and a Mediation Pool. Only the server itself can be deleted.
I am guessing when you delete the FE server, the other pools go away?

Working from bottom up.
Yes, deleting the server will remove the AV pool/mediation servers.
CMS SQL instance. There really isn't a reason or need to remove it. If the server is simply going to be turned off (deleted if VM) you can save yourself the work.
Same with setup. There isn't a real compelling reason to do this but you can if you like.
Lastly, if you are using conferencing on the 2013 servers, I would move your conference directory from 2010 to 2013. I've seen some really strange things happen in environments where people delete conference directories even when they thought no one
was using them. It doesn't hurt to have more than one conference directory and there are a laundry list of reasons to have multiples.

Users still able to sign into Lync 2010 even though their Lync accounts are disabled

I have 2 users who are still able to sign into Lync 2010 even though I disabled their Lync accounts. They no longer show up in the Lync console or when you use get-csuser. Their Lync account were associated somehow with their AD accounts in an old domain
that we just decommissioned. I wanted to delete Lync accounts and recreate to see if that fixed their issue. After deleting the Lync account, they are still able to login. So, I guess I need to edit the Lync database to get rid of them and start fresh?.

Hi Winterthur,
Agree with Tek-Nerd,
this user certificate is valid for a period of 180 days, and is automatically renewed one month prior to expiration regardless of whether the user is connected internally or externally.
Jeff Guillet’s article Disabling a User in AD Does Not Disable the User in Lync provides
a good background about revoking this certificate and properly disabling the user from accessing Lync services when their Active Directory user account is disabled.

Finally about to decomission the Lync 2010 Edge. Small question

Getting ready to finally decommission our Lync 2010 Edge in favor of a 2013 Edge. The only reason I have kept the 2010 Edge around was because we still have a single 2010 FE server. All our users are on 2013 FE servers so the 2010 FE is just sitting there
do nothing. I thought it was best practice to remove the 2010 Edge first and then decommission the 2010 FE.
Does it really matter which server I decommission first? I can't see how but thought I would ask. I am sure there are companies that have 2013 Edge servers with a mix of 2010 and 2013 FE servers but it doesn't hurt to ask I guess.

Hi shadowtuck,
In general, you could decommission the Edge server first.
I don’t think this is a problem, all the Lync 2010 Servers are not working.
And there’s a document about
Uninstalling Microsoft Lync Server 2010 and Removing Server Roles
for your reference.

Re-routing Edge servers from OCS 2007 R2 to LYNC 2010

We have LYNC 2010 Enterprise pool with merged topology with OCS 2007 R2 Pool, using OCS 2007 R2 Edge servers. We would like to move onto LYNC 2013 and here i have some questions on Edge servers.
1. Once I migrate all users, can i keep OCS 2007 R2 Edge servers and decommission OCS 2007 R2 pool to setup LYNC 2013 Pool? ( we have 3 Front end servers and 3 CWA servers in OCS 2007 R2 pool).
Can i use OCS 2007 R2 edge servers for LYNC 2010 and LYNC 2013 Pools for federation and remote access?
Thanks for your help.
Tek-Nerd

I've seen OCS 2007 R2 servers work for Lync 2013 internal users with some limitations. I'm not sure what would happen if you decommission the OCS front end. However, why not upgrade the edge as well?

Mixed environment migration (OCS\Lync 2010 to Lync 2013) retaining BES Integration

Hi All,
I have an existing OCS 2007R2 and Lync 2010 environment which contains BES Collaboration for Enterprise IM on Blackberry devices. I want to migrate this environment to Lync 2013 whilst retaining the BES integration. Understanding that tri-existence is not supported
I've been going through the process of decommissioning all of my legacy OCS servers, which I have now completed, in readiness for starting the Lync 2013 deployment and prepping AD.
Here's my issue - The BES collaboration service was integrating with an old OCS CWA server. I removed the CWA server and migrated the Collaboration service to a new server so that I could configure it to directly communicate directly with the Lync 2010 pool,
however I still needed to install OCS components on the new server in order to achieve that integration. Now I've run the final step of Merging the OCS 2007R2 Topology with the Lync 2010 topology in preparation for deleting the BackCompatSite, the old OCS
servers have gone, but the new Collaboration server has now appeared as a trusted application server within the BackCompatSite. I've done an LDIFDE export of the RTC Service container and have had a look through the contents. I can see that the new BES Collaboration
server is there and that it has an msRTCSIP-TrustedServerVersion value of 4, whereas all the Lync 2010 values are 5, which I'm guessing is what the Lync Topology is using to establish that the BackCompatSite needs to be populated with that Trusted Server entry.
So my question is this - What do I need to do in order to successfully remove the BackCompatSite entry and migrate my environment to Lync 2013 whilst retaining integration with BES and keeping the Enterprise IM service service running on Blackberry devices?
Here's some options that I've thought about - Using ADSIEdit to remove the Trusted Server Application for the new BES Collaboration server so I can merge the Topology and delete the BackCompatSite, although will this break the Enterprise IM service? Temporarily
changing the value of the msRTCSIP-TrustedServerVersion for the Collaboration server from 4 to 5, merging the Topology, deleting the BackCompatSite and then changing the msRTCSIP-TrustedServerVersion back to 4 afterwards? Over a weekend\out of hours, removing
the BES Collaboration server and service altogether, going through the Topology merge\BackCompatSite deletion and then reinstalling the Collaboration service?
Has anyone else gone through this process, or got any advice\experience to pass on before I start working through my list of options?

I've asked this question several times:
Does the 2007 R2 CWA server count as tri-coexistence?
I've asked that both in MCM rotations and directly of people on the PG and the answer is always something along the lines of "nope, it's a trusted app server and not a pool". When I've run into this issue in other deployments, we simply left the backcompatsite
in the deployment into production.
I've never found the above as a publically approved statement just something I've asked previously and been told is OK to do. This is one of those situations that will work but was most likely not tested.
Thanks,
Richard

Uninstalling CMS from Lync 2010

Now that the CMS has been migrated to our Lync 2013 FE servers, I need to remove the replica from our single Lync 2010 server using
Uninstall-CsDatabase -CentralManagementDatabase -SqlServerFqdn <FQDN of SQL Server> -SqlInstanceName <Name of source server>
We plan on keeping the Lync 2010 server around for a bit even though there are no users on it. I have a single Trusted App for webmail integration still attached to the Lync 2010 server which I plan to move to 2013 sometime in the future. Our
Edge is still 2010.
Question is by removing the CMS replica from the Lync 2010 server, will this interfere with operation of the Edge server? All I am doing is removing CMS replica which is something you are supposed to do after moving CMS to 2013 but I am not sure where the
Edge is currently pulling its replica data from. Since the Edge has access to all internal FE servers I assume that if its getting changes from the 2010 FE and I remove that replica, it will get changes going forward from the 2013 FE. Is there any way
to see the Lync FE replication partners so I can verify this?
Eventually, we will build out a 2013 Edge and at that time decommission the 2010 completely. Its a very simple environment. Just IM and presence. No telephony, monitoring or archiving.

You can establish a pool pairing that includes the pool hosting the Central Management store, a backup Central Management store database is set up in the backup pool,
and Central Management store services are installed in both pools. At any point in time, one of the two Central Management store databases is the active master, and the other is a standby. The content is replicated by the Backup Service from the active master
to the standby.

Co-Existence Lync 2010 and Lync 2013

Hi,
How do we check that CMS is moved from lync 2010 to Lync 2013 in Co-Existance environment lync standard edition.
I know that users are moved form Lync 2010 to Lync 2013 but i don't if CMS is moved? And in the existing co-existence we have two edge servers Lync 2010 and Lync 2013. How can i check if traffic is routing through Lync 2010 or lync 2013.
Because we want to Decommission the Lync 2010 STD Edition before doing this i want to make sure every thing go smooth.
Please help me on this.
Thanks
Whenever you see a helpful reply, click on Vote As Helpful & click on Mark As Answer if a post answers your question.

To find out if the CMS is moved:
Get-CsConfigurationStoreLocation, if it's a standard server it will tell you the pool name. If it's an Enterprise server, it will tell you the SQL server name associated with the pool.
http://technet.microsoft.com/en-us/library/gg412814.aspx
Otherwise it's at the top of the topology builder (the top top part that says Lync Server in the left pane, under the Central Management Server spot in the right pane.
For a full decommission article, here's a decent one with screenshots. As Ben said, if you can advise about the other places we could be more specific.

Lync 2010 Recurring meetings don't work post-migration when 2010 server is shut down

I've got an interesting issue here. I completed my Lync Server 2010 -> 2013 migration about 6 months ago, and everything has been going fine as far as I can tell. I left one of the servers up and running in the 2010 pool for a while. I finally decided
it was time to fully decommission Lync Server 2010, so I shut down my 2010 server. I did not delete from the topology just yet, in case something bad happened. Well, when I shut it down, I got reports from some users that they couldn't get into their Lync
Meetings.
The only conclusion I have been able to draw is that this happens for recurring meetings that were scheduled before the Lync Server 2013 migration. It seems that those meetings did not get migrated with the users. Does anyone have any guidance for this situation?
I'm guessing there's no way to actually move the meetings. At best, I'd like to simply be able to identify users who are in this situation and have them reschedule their meetings. I think there are few enough of them that we can handle that.

That's seems odd per:
http://technet.microsoft.com/en-us/library/jj688011.aspx
What is the user experience?
Have you followed all the decommission steps? Have you tried Move-CsConferenceDirectory:
http://technet.microsoft.com/en-us/library/gg412968.aspx
"When you create a dial-in conferencing Uniform Resource Identifier (URI), those URIs are assigned unique SIP addresses. However, SIP addresses are difficult to translate to devices that are not SIP-aware; for example, a public switched telephone network
(PSTN) telephone can’t translate a SIP address. Because of that, Lync Server uses conference directories as a way to help these devices locate, and connect to, dial-in conferences. This is done by creating a SIP conference directory that is associated with
each dial-in conferencing URI, and is identified by an integer value rather than a SIP URI. PSTN telephones and other devices can then use these numbers instead of a SIP URI when connecting to conferences; the directory number is included in the PSTN conference
identification users enter when connecting to a dial-in conference.
Occasionally, you might need to move a conference directory from one pool to another; for example, if you decommission a pool you might need to move your existing conference directories to a new location. The
Move-CsConferenceDirectory cmdlet enables you to move conference directories to a different pool."

Lync 2013 multitenant hosting pack and lync 2010 on-prem - coexistence options, alternative migration scenarios

In post http://social.technet.microsoft.com/Forums/lync/en-US/8a22eed7-cc63-4f9e-b422-3c5a57fb32b0/lync-2013-multitenant-pack-and-lync-2010?forum=lyncdeploy , which was already answered, the answer is no, you cannot migrate from 2010 on-prem. to lync 2013
hosted pack.
Trying to get my head around #1 -why, and #2 -what other alternatives are available.
Lisa answered that there can only be 1 CMS per forest. Is it one CMS per forest, or
one CMS per front end pool in a forest? Meaning you can have different CMS pools. If that were true, we could migrate users to a different front end pool in a coexistence scenario between 2010 on-prem to 2013 hosted pack.
Has anyone done this?
This is tough. I guess a cutover then from 2010 to 2013 multitenant hosted pack would be what?
1. Uninstall 2010, decommission users, decom environment/servers.
2. Fresh install in same AD environment of 2013 hosted pack.
That's tough for our users to make such a transition and have potentially days of downtime.
Is there no other way to do this?
Josh

It is one CMS per forest.
There is no official guide to move from Microsoft Lync Server to Microsoft Lync Server Multitenant Hosting Pack.

Lync 2010 server status shows "Retrieving" in Control Panel

When I open Control Panel on my Lync 2013 FE server, all my 2013 FE servers show a status of normal and a green check mark under replication. For my legacy 2010 server, the status just says Retrieving. Replication with the 2010 is OK. Is this normal? Not
a big deal because we will be decommissioning the 2010 anyway. I don't see any errors in the Lync server log for the 2010.
One thing that is strange though with the 2010 server is I can run setup, Step 2 (Bootstrapper) and it runs fine. Puts a green check mark and says Complete. If I exit and re-run setup, it looks like Step 2 wants to be run again. the green check mark goes
away. CMS has been moved to 2013 about a month ago and everything is fine. Only reason I am keeping the 2010 around is because we are still using the 2010 Edge. Edge is pointing to 2013 FE so I think the 2010 FE is out of the picture completely (no users on
it) but I wanted to keep it around until we stand up a 2013 Edge. 2010 FE is current with cumulative updates.
From the Lync 2010 side, when I open Control Panel, everything looks good. All servers come up green with no issues. Looks like its just the 2013 FE trying to retrieve info from 2010.

Hi Shadowtuck,
the retrieving status you see via the Lync Server 2013 control panel for the Lync Server 2010 front end is normal behaviour
and nothing to be concerenced about, as is the the green tick not showing for step two in the deployment wizard. I have seen this behaviour in all Lync Server 2010 to Lync Server 2013 migrations I have performed for customers. Thanks.
Regards.

After Lync 2010 sql move

hello
after I complete the move of the sql to a new server "http://blogs.technet.com/b/nexthop/archive/2010/12/20/change-a-pool-database-instance-when-the-pool-hosts-the-central-management-server.aspx"
I would then need to decom the temporary front end- I was looking for the procedure?
thanks

Here's the official article:
http://technet.microsoft.com/en-us/library/gg195767(v=ocs.14).aspx
Did you rehome users on the pool, or did it just exist to host the CMS? If it only existed to host the CMS, you can likely just remove it from the topology builder and publish. If it was more complex, you can pretty much follow a migration guide
that walks through decommissioning of an old pool such as:
http://www.oiboran.com/?p=1073. That might be a bit more clear than just reading pure TechNet. The one linked is for migrating to 2013, though the decommissions steps you'd need are for Lync 2010, just skip the ones that don't apply.

Migrating onto LYNC 2010 Edge Servers

We have LYNC 2010 pool merged topology with OCS 2007 R2 and using OCS 2007 R2 Edge pool. All the users have been moved onto LYNC pool and LYNC Edge pool has been setup with same FQDN for acces edge, web conf, andA/V Edge service...
Howver Microsoft Migration guide stated that we need to decommission OCS 2007 R2 edge servers if we use same FQDNs in LYNC Edge? This is confusing to me as how can we decommission OCS edge servers without testing routing on LYNC Edge servers?
Why can't we disable federation with OCS Edge pool ( with deployment wizard) and enable federation with LYNC Edge pool?
Any suggestion or best practice advice to migrate onto LYNC Edge pool is much appreciated.
From MS Migration Guide page 94:
"If your legacy Office Communications Server 2007 R2 Edge Server is configured to use the same FQDN for the Access Edge service, Web Conferencing Edge service, and the A/V Edge service, the procedures in this section to transition the federation
setting to a Lync Server 2010 Edge Server are not supported. If the legacy Edge services are configured to use the same FQDN, you must first migrate all your users from Office Communications Server 2007 R2 to Lync Server 2010, then decommission the Office
Communications Server 2007 R2 Edge Server before enabling federation on the Lync Server 2010 Edge Server.

Not supported means you may have unexpected issue.

Lync 2010 to 2013 migration - Moving the conferencing directory ?

I am in the process of finishing our migration from Lync 2010 to 2013.
Reading the technet page, I don't see any mention to migrate the Lync 2010 Conferencing Directory to 2013.
http://technet.microsoft.com/en-us/library/jj204998.aspx
But doing some quick research, I see that some blog are suggesting of doing it:
http://www.oiboran.com/?p=1219
All my users have already been migrate to the Lync 2013 Pool. No problem so far.
But I am still wondering if the Lync 2010 conferencing should be move or not?
thanks
John

In step 7,
http://technet.microsoft.com/en-us/library/jj688011.aspx
The following user account information does not move to the new server.
Meeting content. In order to move the content shared during a meeting, for example PowerPoint, Whiteboard, attachments or poll data, use the
-MoveConferenceData parameter as part of the Move-CsUser cmdlet.
====
Did you move users with the GUI or with move-csuser -MoveConferenceData?
If you moved with the GUI, the conference data noted above isn't moved. If you think your users would care about this, you could move the directory to 2013 and forget about it. Otherwise, you could just remove it as you decommission the 2010
pool. It's rare that people would care about this data.

LYNC 2010 : Steps to migrate from one pool to another pool

Hi,
We have LYNC 2010 deployed in 2 site (sit1 & Site2)
Currently all user host on Site1 pool. CMS exist in Site1
we have also mediation role and EDGE role on both site.
we have dial in conference on site1.
Currently public DNS record (for edge and as for reverse proxy) point to Site1.
Certificate Authority for site 1 and and site2 is different. However SAN entries and subject name is same for all certificate and bot CA are public CA.
We have to move all users to site2 pool and will also move CMS to site2 and we have to decommission site1.
What is the step by step process to move users, CMS, Edge server Traffic and Mediation server, reverse proxy?
Thanks
jitender

Hi,
The migration process from one pool to another pool is similar for from Lync Server 2010 to Lync Server 2013.
