Is it possible to do the migration from 7.1.5 to 10.5.1.10000-7 which we are doing for jump upgrade from 7.1.5 to 9.1.2.
The reason why I preferred because this jump upgrade we can achieve in isolated network.
In that case can anybody please help to get specific document for that. Kindly have a look on this case.
You can use prime collaboration deployment. PCD will do your upgrade and migration without doing any jump upgrade or intermediate upgrade..
Please refer to the vide below.
All upgrade documentation are available on cisco. Take some time and look at the CUCM 10.5 upgrade document
why to go for Jump upgrade when PCD is available .
You can also do upgrade if using same IP addresses in Non-Production/offline.
Thanks Mr.Ayodeji for your prompt reply. I will check the video.
In isolated upgrade zero down time. But in PCD there is some down time expected.
What is the down time in PCD? PCD will be doing a migration from your current hardware platform to a virtual environment. The upgrade/migration is not happening on the same platform. I am not sure where the down time is.
