The first stage of upgrading to R11.1 SP2 is to upgrade all servers to R22.214.171.124:
•This is absolutely essential. R126.96.36.199 contains changes which are used by the process of upgrading to R11.1 SP2.
•Attempting to upgrade to R11.1 SP2 or higher from any earlier pre-R11.0 release will fail and may cause the lose of data.
1.Backup the servers before upgrading to R188.8.131.52. See Creating a Back Up.
2.The R184.108.40.206 for the IP Office and the Unified Communications Module can be performed using the normal ISO transfer methods. However, refer to the appropriate technical bulletins and release notes for any intermediate releases if not upgrading from another release of R11.0
3.If the servers are already licensed for R11.0, the same licenses are valid for R220.127.116.11 and R11.1 SP2. Otherwise, obtain a set of licenses for the servers at R18.104.22.168.
4.Following the upgrade, test and verify the operation of all services, for example:
oIncoming and outgoing calls.
oone-X Portal for IP Office
5.Only proceed with the R11.1 SP2 upgrade once correct operation of all services has been verified on R22.214.171.124.
6.Begin the upgrade by backing up the R126.96.36.199 servers. See Creating a Back Up.
