DSA backup of databases on TD V14.10 to restore on TD V15.10 is possible or not ? If possible, what are the steps that need to be followed to perform the backup and restore.
Are there any other ways to restore databases from 14.10 to 15.10 ? Or does the restore had to be done at table level ?
DSA can backup from a 14.10 system and restore to a 15.10 system.
Steps depends on what you are planning to do. If you setting up new system then it involves certains pre-tasks.
There are other ways to restore data but the volume of data will be deciding factor in choosing the method.Other options are arcmain,TPT etc.
Restore can be at database or at table level.
