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.
