Viraj Jasani commented on HBASE-26352:
--------------------------------------
Sure [~jacklove2run], I am planning to write the whole procedure sometime soon
(hopefully this month only). However for your case, I would highly recommend
upgrading to 1.6 first because of the huge difference b/ those release lines
(we have spent a lot of efforts for upgrade from 1.3 to 1.6 in the past), I am
hopeful that it should not take much time upgrading to 1.6 for you.
> Provide HBase upgrade guidelines from 1.6 to 2.4+ versions
