I would like to know the safest upgrade path from 3.1.2 to 6.0 using the offline mode? I see that I have a few options and please correct me where I am wrong. Currently using Enterprise edition for RH 6.6
Should I do a straight upgrade from 3.1.2 to 6.0 or should it be done in steps (i.e. 3.1.2 to 4.5 to 5.6 and finally to 6.0)?
What is the guideline for offline mode? Should I perform a backup at 3.1.2 using ccbackup or ccbackupmgr? Should I simply shutdown the CB server though
sudo service couchbase-server stop
and then proceed to install the desired version? I am unable to find the step-by-step guide for upgrade in offline mode.
