  • Communication Manager Release 7.x on AWS.

Note:

For upgrading Communication Manager from Release 6.x to Release 10.2.x, first upgrade the entire Aura Solution from 6.x to 8.1.x, and then upgrade the Aura Solution to Release 10.2.x. You cannot directly upgrade the Release 6.x system to Release 10.1 and later.
