[cisco-voip] CUCM6 MCS to 8.6 UCS bridged upgrade Question

[Kauffman, Christopher]

I have done these upgrades both ways. You could open a TAC case for licensing and in cases like this they have rekeyed all the files into one file for upgrade.  This has the added benefit of streamlining your license files from the point of upgrade since you should now only need the new license and the upgrade license file.

Subject: [cisco-voip] CUCM6 MCS to 8.6 UCS bridged upgrade Question


Hi,

We are planning to upgrade a customer to CUCM 8.6 on UCS from 6.1(3) on MCS.

I understand the upgrade process but the customer has thrown us a curve ball by asking that in order to mitigate downtime on their solution we use a spare MCS server and rebuild it as a Publisher before upgrading to 6.1(4) then 8.6 ready for the DRS backup and restore onto UCS.

They have around 50 x license files which have been added incrementally over the last few years.

My question is whether I'll need to get each license file rehosted to the spare MCS server's MAC or whether I can simply apply for a rollup license from TAC when it's eventually restored on the UCS?

Has anybody been through a similar upgrade experience?

Thanks in advance
