Unity 8.0 & Global Subscriber Manager


I have installed a new unity version 8.0 UM server and was hoping to use GSM and Cobras to migrate the users from the 4.2.1 server over to the unity 8 server, however even having installed the latest available files from ciscosupport, I do not get any move option only delete.

Any one got any ideas or suggestions.  Both servers are in the same domain etc.

Unity 8 homed to exchange 2007 where all users are.

Unity 4 homed to 2003 connector then to the exchange 2007.

Can pass messages between servers fine.



Re: Unity 8.0 & Global Subscriber Manager

According to the compatibility matrix for the various tools on, GSM is not compatible with 8.0.  It is TAC supported so you could verify that with TAC but check here first and see the compatibility.

Documentation for 8.0 does reference using GSM but mostly in the context of deleting VPIM locations, etc.

Re: Unity 8.0 & Global Subscriber Manager


I'm planning to do the same like you in two Weeks:

Use GSM + COBRAS to migrate user from Unity 4.2 to a fresh installed Unity 8.X.

As GSM seems not to be compatible with Unity 8.X, fInally, what have you done?

Thank you

Best regards

Re: Unity 8.0 & Global Subscriber Manager


Firstly I just wanted to say that the Unity 8 upgrade docs imply that GSM can be used, but as we know it doesnt work, so this is what I did.

I performed a COBRAS backup of the users then deleted the user from the 4.2 system  (think I used GSM to do that, but it was a while back now and cant remember).  I then imported the COBRAS information into the new unity 8 system, which noted that the exchange information was there, and ask me if I wanted to create the user, etc.  This worked for the 1200 users I had with only a few users having issues with alias names.

I checked this operation with a couple of users before the big bang approach.
