OCS 2007 R2 to )365 migration

I've Exchange 2007 & OCS R2 deployed in On-Prem, and we planning to moved to O365 and de-commission our Exch & OCS R2. My question once we moved O365, the users who are using OCS how can they access Online lync once we de-commission our OCS and clean
up our local AD. What happens to their Lync attributes? Do we still need lync in on-premise or O365 Lync is enough for voice integration features?
Thanks

OCS 2007 to Lync 2013 migration approach & steps

Hi,
I am looking for migration approach from OCS 2007 (not OCS 2007 r2) to Lync 2013 for 4000 users. as per the MS technet its not supported. has anyone tried and tested if yes please provide the steps and risk involved. thanks

Hi Nmits,
Since it is not supported to migration from OCS 2007 to Lync server 2013 directly, you have two ways to complete the migration process:
Migration from OCS 2007 to OCS 2007 R2 first, then migration from OCS 2007 R2 to Lync server 2013.
Migration from OCS 2007 to Lync server 2010 first, then migration from Lync server 2010 to Lync server 2013.

Just moved from in house ocs 2007 R2 to office 365 lync 2013, I'm clear to "unprep" right?

We've just migrated from in house ocs 2007 r2 to office 365 w lync 2013. We are using dirsync to sync our AD with o365.
We'd like to decommission our OCS 2007 server since its no longer being used. Will running unprep impact our hosted lync 2013 setup given that we are using dirsync? I don't think it should, but just want to confirm.
Any advice appreciated.

Hi MC625,
In my opinion, unprep is not necessary and I suggest you should not perform this action.
I haven't seen an unprep referenced in the migration from OCS to Lync 2013 articles.

OCS 2007 R2 to Lync 2013 migration – The new environment will be in a completely different forest with Lync 2013.

Hi All,
Need help - we are planning to migrate around 14000 ~ 16000 users from OCS 2007 R2 to Lync 2013 environment -
issues are - the new Lync 2013 environment will be in a new forest and sip address will not change.
Considering the same - I understand we don't have any option other than going for a cut-over.
please help me to understand how can I move the user's contact and other configurations from OCS 2007 R2 to Lync 2013.
Thanking you
Maz

Hi,
It is indeed a clean cut over. BIG BANG.
You export all users from your OCS environment. All scheduled live meetings will need to be rescheduled because Lync Server 2013 doesn't support Live Meetings anymore.
I would export, convert and import all users like this:
Dbimpexp.exe /hrxmlfile:"C:\Logs\Lync2010data.xml" /sqlserver:Sql.contoso.com\rtc
Convert-CsUserData -InputFile "C:\Logs\Lync2010data.xml" -OutputFile "C:\Logs\Lync2013Data.Zip" -TargetVersion Current
Import-CsUserData -PoolFqdn "atl-cs-001.litwareinc.com" -FileName "C:\Logs\Lync2013Data.Zip"
Don't use Import-CsUserData twice, but use Update-CsUserData the second time if needed.
Have fun!

Exchange 2007 with pop3 downloader to office 365 migration

Hi,
i would like to migrate my exchange server (exchange 2007) to office 365,
presently i am downloading mails from a online mail service to exchange 2007 through a pop3 downloader and i am distributing this mails locally ( around 20 mail box)
how do i migrate my exchange mails to office 365, is there any automated way to do the same
requesting your valuable suggestions
Regards
Ratheesh
Ratheesh

Hi,
The partially complete in the migration report means there are some items have been skipped due to some reasons. If you check the skipped items, you will see the value is not 0 like other users with status as complete. Usually, this value is not high(1 or
2 in most circumstances) which means only limited items have been skipped.
Hope this helps!
Thanks.

Migrate Notes from Exchange server 2007 to office 365

Hi,
Anyone help me to how to migrate notes from exchange server 2007 to office 365 . My customer having notes on his existing exchange account . We would like to move notes to office 365 .
Please help me or guide me .
Thanks & Regards,
Vinoth

The way you're doing it has two very high hurdles.
First, you have to get the data out of an offline server and into Office 365. That's hardly a trivial task. If the server were online and reachable by the Internet you could use a move request or a third-party tool like MigrationWiz.
Second, if you do get the mail moved, you will want to synchronize the legacyExchangeDN attribute from the old organization into an X500 proxy address in Office 365 for all mailboxes to preserve mail replyability.

Migration to Lync 2013 from OCS 2007 R2 - queries

We are currently running OCS 2007 R2 across Citrix Presentation server 4.5 and Desktops using just IM functionality. We are looking to upgrade to LYNC 2013 for IM and to start using Group Chat. We currently have a Physical OCS front end server,
a physical server running SQL for the DB's and then a physical server running the Archive OCS component.
How easy is this to do? Would we keep the same Pool name?
Can the OCS client be used to connect to Lync 2013?
Can we move the physical servers into VM's? Do we need 3 or can we have all on one VM now?
The SQL DB part can this now be hosted on a stand alone SQL cluster in its own instance if required?
LYNC IM and Group Chat client - is it supported to run on Citrix Presentation server 6.5?
Is a Schema Update required?
Are there any good walk throughs on the internet just covering IM and Group chat migrations etc as from what I have been seeing there are some out there but have voice in them as well.
Thanks.

In addition, the presence and IM features in Office Communicator 2007 R2 are compatible with Lync Server 2013, but conferencing features are not. During migration from Office Communications Server 2007 R2, Office
Communicator 2007 R2 is suitable for presence and IM interoperability, but users should use Lync Web App 2013 to join Lync Server 2013 meetings.
Q: Is it supported to run on Citrix Presentation server 6.5?
A: check the official document at http://support.citrix.com/article/CTX138408
Is a Schema Update required?
Yes, schema update is required. See

Migrating to Lync 2013 from OCS 2007 R2 ... to unprep or not to unprep

I've been reading on TechNet that I should unprep the domain and forest after decommissioning / uninstalling all OCS 2007 R2 server roles:
http://technet.microsoft.com/en-us/library/dd572243(v=office.13).aspx
...but then, in other places (such as blogs and TechNet forums), I've read not to unprep the domain and forest if Lync 2013 is already deployed:
http://social.technet.microsoft.com/Forums/lync/en-US/6b8cd7ca-fe67-418b-ae66-5be682d8d2d6/unprep-ocs-2007-r2-domain-and-forest-with-existing-lync-installation?forum=ocsplanningdeployment
http://www.ucprofessional.com/2011/04/decommisioning-ocs-2007-r2-after.html
Would someone please clarify what to do here and why?

While I haven't personally done a deep dive on everything it does, my understanding is that's it's more than just a simple mod to the system container. For example, from the OCS decommission article you referenced: "Running
Unprep for a domain removes the access control entries (ACEs) granted to Active Directory universal groups". Lync still uses the same RTCUniversal groups, so touching it at all with Lync in production as well could be bad.
Forest prep actually creates these groups:
http://technet.microsoft.com/en-us/library/dd441353(v=office.13).aspx That said, I haven't seen an unprep referenced in the migration from OCS to Lync docs, and the doc you referenced is specifically for completely removing OCS from your environment
where these groups wouldn't be needed. So, while I can't tell you exactly what all it does, I really wouldn't mess with it unless you have a strong reason to or are willing to rebuild Lync to get a few old objects out of the system container.

Upgrade from OCS 2007 to OCS 2007 R2 and Lync 2013

Hy friends!
Help me, please!
Scenario: Migration from OCS 2007 RTM to OCS 2007 R2
Target: Keep user contact list (I'm talking about only OCS contact list from internal organization users, I'm not refer about external addresses)
Question: I want to know if when I move a user from OCS 2007 RTM to OCS 2007 R2 the user contact list is also migrated?
If Yes, can you share the Microsoft documentation that describe it?
So, after I migrate the users to OCS 2007 R2, finally I can do a supported migration to Lync Server 2013.
Thanks in advance.

If you do a side-by-side migration the contact lists (and other user data) should remain intact. If you tear down OCS2007 and then install OCS2007R2, then you will need to use dbimpexp.exe to export the contact list from OCS2007.
Here is an overview: http://blogs.technet.com/b/ucedsg/archive/2009/02/07/how-do-i-get-from-ocs-rtm-r1-to-ocs-r2.aspx
Also take a look at the deployment guide: https://www.microsoft.com/en-us/download/details.aspx?id=19984 specifically
the section called "Updating from Office Communications Server 2007" which lists some potential issues.

Exchange 2007 to Office 365.

Hello,
We're upgrading our Exchange 2007 to Office 365. We can't store a small portion of our emails in office 365 (cloud) due to contract obligations that says storing data outside of the UK is not allowed.
I can see there is a way to create a pst on a network location to store this small portion of data but when my pc is away from the office network, i receive an error saying it can't find the PST. Is there a way to stop the error appearing? I only want the pst folder to appear if they are on the office network? Or do you have a different solution i mind to solve our problem?
Thanks

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?

OCS 2007 R2 and Exchange 2013

Cannot find any information about this. I cannot find anything on OCS2007 R2 with Exchange 2013.
We have OCS 2007 R2 with Exchange 2007. The plan is to migrate Exchange 2007 to Exchange 2013. We configured new Exchange server and migrated test user. Now caller cannot reach voicemail for the test user.
We are planning to migrate OCS to Lync 2013 in a couple of months, but we wanted to migrate Exchange first.
Any ideas what to do?
Thank you. Eric.

Is your OCS 2007 R2 environment updated to CU 10 or above? http://technet.microsoft.com/en-us/library/jj851069(v=exchg.150).aspx

How to connect Lync 2013 client with OCS 2007 R2 Edge server

Hi,
We have OCS 2007 R2 Edge server for external & OCS 2007 R2 FE Server for internal access in our environment.
We able to access internally Lync2013 clients with OCS 2007R2 server, however from external we cannot access Lync2013 client with OCS2007 R2 server.
Is there any patch or registry key trick to access OCS from lync2013 client externally? We cannot immediately migrate to Lync2013 server from OCS.
Any help
MD

Hi,
I suggest you still use OCS 2007 R2 client to login OCS 2007 R2 Server untill finishing migration to Lync Server 2013, as using Lync client with OCS 2007 R2 Server will offer a pretty limited experience.
Here is a great blog about Lync 2010 Client unsupported with OCS, it is for Lync 2010 client but similar for Lync 2013 client:

OCS 2007 to OCS 2007 R2

Hello world.
Doing a side by side migration from OCS 2007 to OCS 2007 R2 (due to our goofy SA agreement cannot upgrade to 2010 or Lync yet) and I am following the step by step guide here:
https://technet.microsoft.com/en-us/library/dd572505(office.13).aspx
My question is this...can I have two disparate SRV records referencing TLS...one pointed to legacy and then a new one pointed to the new server? What will happen with my clients?
This is an internal only deployment...no edge servers...no director...etc.
I have the domain prepped and when I launch setupse.exe I get all the way to the end and it rolls back because it cannot create the pool as it does not exist and there is no SRV TLS record to reference the pool.
We use OCS 2007 extensively throughout the org day and evening so I need to be able to get the new SRV records and pool inline without impacting production.
Can anyone shed some light on how I move forward? Been over the documentation and Google/Bing quite a bit and have yet to find a sufficient answer.
Thank you in advance MS community!

Hi crashIO,
No, the DNS SRV record can point only to a single pool, and in a mixed environment the supported configuration is to use Office Communications Server 2007, Director, with both Office Communications
Server 2007 and Office Communications Server 2007 R2 pools. This means that during migration, you should configure DNS records to point to the Office Communications Server 2007 Director or FE.
Before installing the OCS 2007 R2 pool, did you move your OCS Global Settings from the System Container to the Configuration Container in Active Directory.
“With Office Communications Server 2007 R2, the default container for Office Communications Server global settings is the Configuration container. In previous versions, the default container
was System container of the root domain.”
If you did not perform this step, please follow the article below to do this.
https://technet.microsoft.com/en-us/library/dd572392%28v=office.13%29.aspx
In addition, in order to co-existence with OCS 2007 R2, please ensure your OCS 2007 Servers are up-to-date.
Best regards,
Eric
