We plan to upgrade a CUCM cluster 4.2(3) to 7.1.

Currently, some users are logged with their UDP profiles to their phones.

My question is: Will these users remain logged after the upgrade with DMA?

Thanks for any help.

Hi Alban,

Kindly the upgrade is recommended to be done in a downtime in order to not affect the users

Your configuration will be as it after the upgrade complete, so your users will be able to login again to their device profiles

Only remember to be aware that your customer background images, custom TFTP files, custom MoH files, and customer ring tones do not get migrated during the upgrade process. You must reinstall these files after the upgrade completes

Please find this good link for more information about this upgrade:
