Uninstall Legacy Lync 2010 enterprise and install Lync 2013

I have a customer who has Lync 2010 enterprise and decided to install Lync 2013 but don't want migration and instead want to uninstall Lync 2010 . I would like to know in this case how to clean the active directory schema from Lync 2010 ?
and If there's anything else to consider before uninstalling Lync 2010 ? I will have to disable/remove all currently Lync enabled users but is there anything else?
I found this article, but would like to know what's the steps in sequence of removing Lync in this case?
https://social.technet.microsoft.com/wiki/contents/articles/9849.how-to-remove-lync-server-2010-from-active-directory.aspx
for example, do I have to first
1- Disable LYnc users.
2- Uninstall Lync server Application from Control panel
3- Remove Lync from Active Directory?
Would appreciate your help. thanks
thanks

Move cms from Lync 2010 enterprise pool to Lync 2013 enterprise pool

Hi!
We recently moved all our users from our 2010 ent pool to our new 2013 ent pool.
we have read the http://technet.microsoft.com/en-us/library/jj688013%28OCS.15%29.aspx
In step 7, it says that we should run the deployment wizard. Do we have to do this on all servers in the pool?
regards,
Uc

Hi,
yes you should run it on all front-End servers in the pool

Lync 2010 client and Office 2013

I have Office 2013 installed minus Lync 2013 and have Lync 2010 installed in its place, we have a Lync 2010 infrastructure and are planning on upgrading our customers’s workstations to office 2013 and maintaining the Lync 2010
clients.
Is it expected behavior in this scenario to get prompted with the “Join the meeting using your web browser”, “Download and install Lync Attendee” & “Use Communicator” page when attpempting to join a meeting?
Thanks….

Thanks for the reply.
The reason that we though to stay with the Lync 2010 client is that we were told that the Lync 2013 client only communicates to the Lync 2010 back-end via the Lync Edge servers. In looking at the Lync 2013 client configuration
information I see that Inside User Status: True which looks like it might not be communicating via the Edge servers.
Is this a valid reason not to push forward with Lync 2013 client while still having Lync 2010 back-end?
Thanks…

Just download, install, and activate using your serial number. You are allowed to have the software installed and activated on two machines. If you do not wish to retain the original installation as a backup you can deactivate it by opening one of the programs and choosing Help -> Deactivate.
Here is a general link for where you can find download links...
Download and Installation Help -
https://helpx.adobe.com/download-install.html
If you would like a more direct link you will need to name the software and the version.
If you need your serial number you should be able to find it in your Adobe account online if you registered the software when you first installed it.

How to remove OCS and install lync 2013 on MS Office 2007 and 2010

Hi,
We need to install lync 2013 on our systems having office 2007 and 2010 via SCCM 2012.
Please suggest.
Regards, Syed Fahad Ali

Lync 2013 no longer has its own installer, but instead uses the Office installer. You can create a customized installation and deploy it just like you do with Office:

Lync 2010 server and UM role on different domains in different forests

Hello
I have a Lync 2010 environment running on domain A, with exchange 2010 UM also running in Domain A. We are in the process of migrating users and mailboxes from domain A to domain B. Once we reach our enterprise voice users with exchange UM enabled
we will need to install the exchange UM role on the exchange server in Domain B.
There is a 2-way trust relationship between domain A and domain B.
All the users from are running Lync on a PC located in Domain B, using Lync credentials from Domain A.
Are there any issues running Lync 2010 and Exchange UM from different domains in different forests? Is it as simple as creating a new UM DialPlan and UM IP Gateway to the domain A Lync FQDN?
Thanks

Hi,
Each UM forest must be configured to trust the forest in which Lync Server is deployed, and the forest in which Lync Server 2013 is deployed must be configured to trust each UM forest. If Exchange UM is installed in multiple forests, the Exchange
Server integration steps must be performed for each UM forest or you’ll have to specify the Lync Server domain.
Here is a link about for UM of Lync server 2013 but similar for Lync server 2010:

LYNC 2010 Enterprise Pool Front End Servers

Can we mix Windows 2008 R2 Enterprise Edition and Standard Edition virtual servers in same LYNC 2010 Front End Pool?
Tek-Nerd

Agree with Lisa,Lync Server virtualization supports a mix of operating systems. For example, a host server running Windows Server 2012 R2 that runs virtual servers that run Windows Server 2008 R2 is supported.
You cannot mix different types of servers within the same pool. All servers within the same pool must either be physical or virtual

Replication issue between lync 2010 FE and lync 2013 FE

Hello
I face any issue in my lync server's .
I was in the last steps in the migration process from lync 2010 to 2013 enterprise edition .
where CMS was moved already to 2013 , and later on many time I checked the replication and it was fine , then I deleted the CMS DB FROM 2010 FE and I checked the replication and it was fine .
later on I proceed to delete the archiving server and monitoring server and it was fine .
later on I proceed to
Reset call admission control
Prevent sessions for services
Stop Lync Server 2010 services
Remove a Front End Server from a pool
I just I face this replication issue after I start the process to delete the lync 2010 pool which im stuck on it now .
one more thing while I was trying to delete the 2010 front end pool , I got the error .
Error: An error occurred: "System.InvalidOperationException" "Cannot publish topology changes. Conference directories still exist on a pool that would be deleted. Remove the conference directories before continuing."
so I moved the conference directories from 2010 pool to the 2013 pool successfully.
but later on when I check the replication I notice the replication issue ?

I'm not doing any change on 2010 pool now (I just try to delete it ) , all the change it is on 2013 pool .
for edge server 2013 I shut down the server since there is another configuration issue there (so replication to edge server not the issue now since it is down).
my question is this will affect my lync 2013 since it is the production now ? is this un completed steps for removing the 2010 pool affect my production.
is the replication issue affects my 2013 pool ?
Kind Regards
MK

Hi,
From your description above, did you mean before deleting the Lync Server 2010 Pool from topology, you found the replication of Lync 2010 FE Server not update to date?
If it is the case, based on my knowledge, there is no affect for Lync Server 2013 Pool. Please double check if Lync Server 2013 Pool work normally, and Lync users in Lync 2013 Pool can use all Lync function without issues. Then you can delete Lync 2010 Pool
from Topology and publish it. After finish it, please re-run step 2 on Lync Server 2013 FE Servers.

Lync 2010 client and SRV record

When Lync 2010 was originally set up in our environment, we included our login domain which is a .local as a SIP domain but everyone uses our additional SIP domain which is a .org.
In our internal DNS, we have SRV records under both domains. Question is if a Lync 2010 client is doing autodiscover and their SIP domain is the .org, will the client look at the SRV record in the .local domain? I don't think this SRV record was ever used
even though its the users login domain, its not their SIP domain.

You're right, the SRV records that belongs to your .local domain are not used by the lync client for a user that hs a .org sip domain sign-in address, so as you are saying if all the users are configured with a .org sip domain that means these SRV records
were never used, and you can safely remove them.

Lync 2010 Edge and TMG

I have an issue where a large group of users (about 2k) have been 'migrated' into my environment without first migrating their accounts in AD. Basically, accounts were created internally and they are just connecting to my Lync 2010 and Exchange 2010
environment through the internet.
Problem is, when they leave their current network, they hit my TMG 2010 servers from a single IP address. This triggered TMGs Flood Mitigation settings and their IP was blocked. I fixed this by creating an exception for their IP address
and bumping up the number of allowed tcp and http connections per minute.
Now, we are still having issues with users that attempt desktop and application sharing. Their sessions close sporadically.
My primary question is, has anyone ever attempted this type of solution before, allowing thousands of users external access from a single IP address through TMG and Lync Edge? If so is it supported and what type of issues might I need to look
for? Does the Edge role also have restrictions on how many connections can be made by a single IP address from the internet?

Hi Ray,
I'm pretty sure TMG is generally not the external endpoint publishing the AV/Sharing capabilities unless it is drastically different in your environment (or if TMG is your outer most firewall)
Usual setup for reverse proxy is :
Firewall1 (outer most) <---> DMZ <----> Firewall2 (TMG?) ---> Corp
Firewall 2 publishes web services.
Edge usually looks like:
Firewall1 (outer most) <---> DMZ <----> Edge Access/AV/WebConf ---> Corp
Can you confirm if TMG is your outer-most firewall? If it is then check if your edge has one or multiple IPs. Then check the publishing for those IPs and make sure they adhere to the exception you created. In addition, check the Firewall on the edge server
itself.
If TMG is not your outer-most firewall (if Firewall1 is some other device) then please check the intrusion protection on the Firewall1 device and allow for exception in there as well.
Hope this helps.
Cheers,
Max

How to uninstall Office 2010 32 bit and install Office 2013 64 bit

Hi Everyone,
I am rather new to SCCM. I have setup a SCCM 2012 SP1 system. I am now trying to setup an Application where it will install Office 2013 64 bit. Everything seemed to go smoothly until I tried testing it. I received an error that I
cannot install the 64 bit version of Office 2013 because Office 2010 32 bit is already installed.
I tried to modify the MSP where it will uninstall Office 2010 before installing Office 2013 but apparently as soon as it starts it checks for the 32 bit installation and exits when it finds it.
Could someone give me a detailed solution (since I am new to SCCM)?
Ken

While referring to older versions of office I think this link may apply: http://social.technet.microsoft.com/Forums/en-US/f255e17d-4e1f-4231-8a88-d63f41c83c52/how-to-automatcally-uninstall-office-2007-32-bit-for-installation-of-office-2010-64-bit?forum=officesetupdeployprevious
Also you might create an office 2010 package, with an uninstall program that removes it.
Then in your office 2013 package make the uninstall for 2010 to be run first.

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.

Lync 2010 client - Cannot access lync server as a remote user

Just one simple question. I cannot login to my lync 2010 server because from my location I cannot reach directly from my client the edge server on port 443. Can I still login to lync if using an internet proxy, I know that using an internet proxy,
with another ip I can reach the internet and so I can reach also the edge server public address on port 443. But I don't know if lync client for login read also internet proxy settings.
Hope it's all clear. Thanks for your support

As long as you are able to reach Internet and your edge is configured properly, you will be able to connect. Lync client doesnt have proxy settings

ITunes 10.2 Upgrade fix temporary. Fix to iTunes 10.2.2 by uninstall Apple Mobile Device Support and install AMDS from 10.0. Worked only to fail in 5 days. iTunes back to very slow to open and will not see device (iPhone) connected. Sorry

I was one this site for 20+ Days and found a fix for 10.2.1 when it failed. I Uninstalled all, following other attempts that failed, then installed latest Version from Apple iTunes 10.2.12. I then uninstalled Apple Mobile Device Support (AMDS) and installed AMDS from the older 10.0 version of iTunes. Success it worked. Today, I am now back to old problem, iTnes takes very long time to open and fails to see my device when connected (iPhone). I really only have iTunes for my iPhone no extensive library a few hundred CD's in music location and no podcasts. I have less than 6 moveis and want to update them now. I am willing to lose all in iTunes library if need be just to get computer to see G3 iPhone with iOS 4.2 and let me synch once again. I like security of backup too. It older iTunes may now not support, that too is OK. I still want to get the 3GS (no 4G desires, yet) and do not care if any of it is the latest from Apple as long as it works.

Hi Erik,
Your basic suggestion actually worked for me. But this is what I did for others who are having issues removing/installing etc.
1. Download the latest iTunes 8.2. You should end up with a file iTunesSetup.
2. If you dont already have WinRAR, download free copy from http://www.rarlab.com/ and install.
3. Right click on iTunesSetup and choose "Extract" to somewhere you know. eg C:\itunetemp
4. Open up folder where you extracted iTunesSetup and double-click applemobiledevicesupport.msi
5. It should ask you if you want to repair or remove... choose remove.
6. REBOOT your PC.
7. Go back to where you extracted iTunesSetup and double-click applemobiledevicesupport.msi and go through the install.
8. Plug in your iPhone.
If all is well iTunes should automatically start and start syncing your iPhone.
Goodluck all!
Cheers.
