Description Marina Kalinin 2016-11-07 03:54:58 UTC 
Today, the guide says:
"The data center and cluster compatibility level must be at version 3.6 before attempting the procedure."

However, one of the known issues to fail the upgrade to 4.0 is not to have ALL the clusters and Data Centers in the upgraded environment set to 3.6. For instance, some customers do not use the Default Data Center, so they may ignore it and keep it in 3.3, for example.


Suggested wording: 
"All Data Centers and clusters in the setup must be changed to 3.6 CL before attempting the procedure."

Also, maybe it is worth adding "Important" Note for it?

Assigning to Byron for review.

Byron, this is a quick change to make it more clear that ALL data centers and clusters in the environment must be at version 3.6 before an upgrade to 4.0. This should be applied in the standard and SHE upgrade instructions.
