Migration from Prime Infrastructure 3.4 to 3.9 or 3.10 - licenses?

[andrew.butterworth]

I have a customer with PI 3.4 installed (ESXi VM).  They need to upgrade to a minimum of 3.8 to support some new hardware (C9500-24Y4C-A switches).  I have looked at the release notes for versions 3.4 thru 3.10 and can see a sort of path.  3.4 -> 3.5, 3.5 -> 3.7 and 3.7 -> 3.8.  If they want to go to 3.9 then they can't as it was initially built with 3.4 and won't work because of the underlying Red Hat 2.0 OS.

To go from 3.4 to 3.9 (or 3.10) they would need to upgrade from 3.4 -> 3.5, 3.5 -> 3.7 and do a backup.  Deploy a fresh 3.9 (or 3.10) PI instance and restore from the 3.7 backup.

What happens with licenses in this scenario?  Is it all Smart Licensing and therefore just a case of removing the old product instances on software.cisco.com and letting the new PI 3.9/10 server register and consume the released licenses?

The documentation for all versions 3.4 to 3.10 mentions license files, which surprised me a bit if its all Smart Licensing?

Any takers?

You can use the below thread for upgrade 3.4 inline upgrade to 3.7 and fresh installation of 3.9 and restore appliance back of 3.7.

3.9 you can use still old PAK License, but if you migrate to pak to smart License, i do not believe you can not revert.

but manual license still works until 3.9

(make sure you take the License backup)
