Dears,
Newly I have upgraded CUCM from 7.0.2 to 7.1.3. First I applied iso via sftp to publisher, then to subscriber. I cheched MD5sum it was correct. When I reboot CUCM and grub menu displays I have no ability to check now partition. I can not even press any button like the keyboard is not working. But it does because I am able to login the console. Why issue such this could happen? I can see both of active and inactive partitions from show system version active/inactive.
Can I use utils system switch version to switch it first on subscriber then on publisher to minimize the downtime?
We made a few changes to CUCM configuration. If I will take a backup now can I reciver it whan I'll boot from new 7.1.3 partition?
Tahnk you all.
