We have 1 Main TEPS and another Backup TEPS with 3 read only TEP enviroment in our environment.

TEPS Master - Read Only TEP --Read Only TEP
|
TEPS Fail over.

Any idea how to synchronise between TEPS.

Mostly we will do the changes in the MASTER TEPS and we want a method so that all the TEPS will have the same data at any point of time.

Need your help.
