Nitin,
There's some info on how to upgrade on the wiki at [1] and [2]. If
your 0.9aXXXXXX version has XXXXXX < 753448 you'll need to use the
Ruby script at [2]. Otherwise you should be able to use couchdb-dump
and couchdb-load from couchdb-python or run two couchdb nodes and
replicate from the old version to the new version. If you're two
versions span that commit then you must use the Ruby script because
replication changes as well.

Hi Paul,
Thanks much for those links and I hope to get to the point where I can
use them. Currenty I only have my data in files with
a) no older couch instance running and what's worse,
b) no idea what version I was running in my old couch, although I know
it was a 0.9a<something> from trunk.
so I guess my question becomes
a) how do I know just from the database binary files what exact couch
version created them - is there some util or a specific set of bytes
in the header or
some voodoo that I can use and then I can go install that specific couch
version from src. Then use the database dump/load scripts.

Hi guys,
This a rather strange situation but I need to get out of it :-)
I had a few Gig of data in a 0.9axxxxxx version.
I wanted to upgrade couch to 0.9 tarball when it was released.
I wasn't sure how it would go so I made a filesystem level backup of the
data directories.
Then when 0.9 installed and was running fine I copied one of the databases
from the old backed up dir to the new 0.9 couch's data dir.
I got a "bad version" error from which I gather that the older version data
is somehow not binary compatible with the newer one.
I don't have a running older version couch - and it was installed from src
anyway and I have no idea what minor rev of 0.9a it was.
So how do I recover the old data from my files and upload it to the new
version.
Any ideas ?
There's a lot of data in there and I absolutely need to get it out - help!
