We need your technical assistance for one the task which looks some critical and challenging. Hope I get the most appropriate and best technical suggestion from Cisco Experts. Here are details for the task:
Current Call Manager Version
System version: 22.214.171.12400-4
Intel(R) Pentium(R) D CPU 2.80GHz
RAID not configured
We need to upgrade it to Call Manger 9 in virtual environment for this propose we took UCS-EZ7-C220-E. First we need to know that what the possible options of migration?
Further this is working environment and we need to consider the data migration of Call Manager. If you required any other information then kindly let me know so I can provide.
Symptom: Cisco Unified Communications Manager (CUCM) jump upgrade from 6.1(5) to 9.1(2) fails with "Error detected in post-install phase. Trying to restore the system to the active version. Please wait".
Conditions: No NTP server is configured on CUCM as an NTP reference. An NTP reference was not required on 6.1(5) but is required on 9.1(2) so the upgrade fails if an NTP reference is not configured on CUCM 6.1(5) prior to the upgrade.
If the system fails to switch back to 6.1(5) and gets stuck with an error on the console: ---------------------------- Checking filesystems fsck.ext3: Filesystem has unsupported features(s) (/) e2fsck: Get a newer version of e2fsck! . . . *** An error occurred during the file system check. *** Dropping you to a shell; the system will reboot *** when you leave the shell. Give root password for maintenance (or type Control-D to continue): ----------------------------
Contact the Technical Assistance Center (TAC) and reference CSCty45858.
Workaround: Add an NTP reference to CUCM prior to the jump upgrade from 6.1(5) to 9.1(2)
3 Upgrade to Unified Communications Manager Release 9.1(x).
We have hardware platform 7815 (I2) so for this platform we can move to upgrade 8.0(3). but after this point we cannot move to 8.0(3) to make it virtualized on same hardware due to compatibility restriction. So its mean from here we will do physical migration from MCS to UCS, so how we can shift 8.0(3) Call Manager to UCS to make it virtulize and then move to 9.x?
Either we install a fresh CUCM 8.0(3) unvirtulize and then do backup installation of MCS on new UCS with CUCM 8.0(3) un virtulize and convert it to Virtulize?
With Drive to 9 you can virtulize your current version 6.1 and then go through the upgrade, you dont need to perform the upgrade on your current server. Just remember to reinstall and restore from backup after you finish the upgrade as documented in order to align partitions appopriately.

No. You will only need the SRST licenses on the primary router. Because this feature...
