we have cucm and IMP 9.1
we planning to upgrade them to 10.5 ,but the current setup is IM&P (Restrected) and CUCM (UnRestreicted) is that supported? can we proceed with upgrade? or we have to upgrade cucm them rebuild the IMP from scratch as unrestricted?
What do you mean by IMP restrected and CUCM unrestrected?
In the normal case and most of the time you don't have to rebuild IMP from scratch just recover it .
Please rate if it help.
Thanks Deepak , great one , but how we can now solve the issue? can we proceed with upgrade to 10?and from IM&P (Restrected to unrestricted?
You should be able to upgrade from restricted to unrestricted because there is no mention about this thing being a problem in the Upgrade guide.
The guide does mention about the inability of upgrading from Restricted to Unrestricted but not the other way round. Though you can still check with TAC for a final confirmation.
You can go from restricted to unrestricted when doing an upgrade, do bear in mind that is a one way street, if at a later time they want to use restricted, that will mean a rebuild will need to happen, and you'll need to manually migrate all the info via BAT.
