1. Has anybody done an inplace upgrade form 8.6.2 to 10.5 using PCD? We are already running 8.6.2 on a C210 and want to upgrade to 10.5. I see it listed as supported, but there is very little info, most everything is about a migration. Running CUCM 8.6.2 and CUPS 8.6.5
2. Any problems rolling back to 8.6.2 from 10.5, if there is a problem?
3. Will PCD make the necessary modifications to the VM machine during the upgrade? If not do I do them before or after upgrading to 10.5?
Need your expert advice, im planning upgrade this weekend, Im not going with PCD rather through OS admin of upgrade
Im going through documentation on upgrade release notes. I see the is refresh upgrade from 8.6 to 10.5 with some config changes on virtual machines like increasing the disk size on second one, changing the Guest OS of VM to RHEL 6 [64 bit ] and changing NIC adaptor to VMXNT3 etc as pre upgrade task
Now my question is CUCM 10.5 ver requires VM machine with 1 X 110 Gb Vdisk while existing 8.6 is with 2 X 80 Gb vdisk. OVA readme txt file for 10.5 says do not attempt to change disk size or number while upgrade release note says increase disk size.
