CUCM Hardware Migration 8.6 to 11.5

[Ehab.Shaqoura]

Dear All ,

I hope that you doing well .

My customer have a CUCM cluster " PUB, 1 Sub " Version 8.6.2.20000-2 on hardware model " R210-212160sw " , we have a new Cisco Business Edition 6000 servers and we need to migrate and upgrade the cluster to 11.5 version with 1 PUB , 2 SUB  , the IP Phones getting IP using DHCP and static for some remote site .

I need a help on how I should proceed with this exactly , is there a possibility to upgrade to 11.5 then backup and restore to new same version on new Hosts , or backup and restore to 8.6 on the new Hosts Pub then build a cluster , or what exactly should i do  ? 

Thanks

Either option is valid, you can also use PCD to migrate directly to 11.5

Thank you for reply .

I'm just need to make sure if the current hardware support cucm 11.5 ?

Assuming you want to upgrade and then move, yes, your current HW needs to support the target version.
