Upgrade from 4.1 to 7.1.5 - DMA Extention Mobility problem

Level 1
Level 1

We're gonna upgrade our cluster from 4.1 to 7.1.5. The question is ,we have around 10,000 users with extention mobility (EM),

Is DMA gonna export user-logged-in information , as well? So that, when the upgrade process is done, no one needs to log into the phone again?

I found a couple of documents saying that

CallManager 4.x to 5.x/6.x Upgrade Fails Due to DMA Error


Before you start the DMA backup, make  sure that ALL Extension Mobility Users are "logged OUT". If any of the  users are logged into Extension Mobility, the DMA backup will not  succeed.

Release Notes for Cisco Unified CallManager Release 5.0(3)

DMA does not export the last user-logged-in data for CallManager 5.0.3.

But these documents do not show that problem for ver 7.x.

Any help would be greatly appreciated.

You have to log them out before running DMA, here's an enhancement to add a bulk logout feature:

Thank you for your prompt response.

We ran DMA in our production site without loggin the users out, it took about 18 hours (3 GB size), and didn't give any error about that. Do you think we still have to log all user out before running DMA regardless of giving any error or not?

And is there any document showing this problem for 7.x migration?

I really thank you for your help.
