Data migration 0.20 -> 0.89 Q
Hi,
I tried to find the info on data migration from 0.20 to 0.89 and so far
wasn't successful.
I noticed that migrate utility is not in the code base for the 0.89 anymore.
is there a way or howto somewhere about how to migrate compacted 0.20 tables
to 0.89 tables?
Thanks in advance .
Dmitriy
PS. i am trying to migration from 0.20.5 to 0.89-rc1-stumbleupon+yesterday's
HRegion patch
Thank you .

hi,
there is no migration to get to 0.89 from 0.20.x. However be warned
you cannot go back, this is because there are non-backward compatible
changes in how we name region directories, so the first split you have
will create region directories that 0.20 wont know about.

Thank you, Ryan, Jean-Daniel.
That's extremely nice. I don't care about going back so much.
One question though -- in the case of going back -- are export routine
formats compatible or i'd have to pump the data thru a format of my own if i
want to re-flush it back?
Thanks.

Sorry, no migration as in there's nothing special to do... it just
works. And like Ryan said, no coming back.
