3.6 EL6 migration to 4.0 EL7 works OK for me with following steps:
1. 3.6 EL6 engine (3.6 dc/clstr level)
2. 3.6 EL6 engine-backup and do backup
3. 4.0 EL7 clean install
4. 4.0 EL7 engine-backup and do restore
5. 4.0 EL7 engine-setup
What are the problematic steps on other side?
Do we have a problem if 3.6 EL6 engine does have dc/clstr level set to '3.5'?
