Migrating from LCS 2005 SP1 to OCS 2007 R2 - which client can you use when?
This is an update to my my previous post on migration https://blogs.technet.com/jenstr/archive/2007/11/27/migrating-from-lcs-2005-sp1-to-ocs-2007-which-client-can-you-use-when.aspx. I’ve only updated the table. For the full details please refer to the previous post.
| Row | Client connects with | User homed on | Enabled for Enhanced Presence | Enhanced Presence Mode set | Connection works? |
| 1 | OC 2005 | LCS 2005 SP1 | N/A | N/A | Yes |
| 2 | OC 2007 OC 2007 R2 | LCS 2005 SP1 | N/A | N/A | No |
| 3 | OC 2005 | OCS 2007 OCS 2007 R2 | No | No | Yes |
| 4 | OC 2007 | OCS 2007 OCS 2007 R2 | No | No | No |
| 5 | OC 2005 | OCS 2007 OCS 2007 R2 | Yes | No | Yes |
| 6 | OC 2007 | OCS 2007 OCS 2007 R2 | Yes | Yes (sets it on first successful connection) | Yes |
| 7 | OC 2005 | OCS 2007 OCS 2007 R2 | Yes | Yes | No |
| 8 | OC 2007 R2 | OCS 2007 | Yes | Yes | No |
Some key points to note:
- OC 2007 R2 can only connect to OCS 2007 R2
- Users homed on OCS 2007 R2 can chose between OC 2007 and OC 2007 R2
