Hello and thank you for takign the time to read my question. We are upgrading from Callmanager 4.0(2a) to new hardware and the latest version. Let me throw this plan out there and please let me know if I am on track.
We have Callmanger 4.0(2a) and would like to upgrade to the newest version, at least to CUCM 8. We already have the new hardware that is compatible, smartnets and licenses. After looking at the matrix sheet it appears (there were several different upgrade routes but I could only find documentation for upgradring to 7.1(2) and 7.0(1) from 4.x so I am going with 7.1(2)) should we go:
from 4.0(2a) to 4.3(1)
from 4.3(1) to 7.1(2)
from 7.1(2) to 8.0(1)
this gets us to 8 which we can then upgrade to 8.5 or 8.6
So, we have 4 servers, 2 old (Pub, Sub) and 2 new (Pub, Sub). What is the best plan of attack here:
1) Backup 4.0(2a), then do an inplace upgrade on old hardware from 4.0(2a) to 4.3(1). Then backup 4.3(1) and do another inplace upgrade on the same server to 7.1(2). Then load 7.1(2) on the new hardware and restore backup from 7.1(2) on the old hardware. Then backup and inplace upgrade to 8.0 on the new server?
Or
2) is there any way to not have to “touch” or do an inplace upgrade on the old hardware running 4.0(2a), and just run a backup on it, load 8.5 on the new server and import the data over from the backup?
Any suggestions on a plan of attack here? I thank all of you experts in advance for your help!
