CUCM Upgradation 7.1.5 to 10.X

[Siva chinap]

Planning to upgrade CUCM 7.1.5 to 10.X version,which is the best practices....my plan is to upgrade 7.1.5 to 8.x version in MCS server

Install a 8.x in UCS server restore the backup and upgrade to 10.x version.,

Another plan is to upgrade 7.1.5 to 10.X  through PCD?

Which is the best practice, which leads less down time?

[Jaime Valencia]

PCD is by far the best option, you also avoid all the VM changes between upgrades and all the pre-req COP files.

When i upgrading 1000 IP Phones to new UC Phone, should i register all the IP Phones manually.

[Shadi Shami]

you have the option to get the same IP addresses for the new servers as the old ones, in this case no changes required to get the phones registered to 10.5. if you choose to get new IP addresses, then you need to update phones' dhcp pool by setting option 150 into 10.5 ip address.

My another plan to install CUCM 7.1 in UCS server, restore the backup upgrade to 8.5

from 8.5 version upgrade to 10.5 take a drsbackup

Deploy new CUCM 10.5 in VM restore the backup.

Any suggestion on this upgradation?

[Manish Gogna]

Install of CUCM version 7.x on UCS is supported only for jump upgrades to version 9.x or 10.x. So, you should look at upgrading to version 9.1.2 or higher from 7.x instead of 8.5.

That should be fine. You can check the upgrade guide for version 10.x for relevant details.
