1.8 -> 2.0 data migration
Tue, 10/16/2012 - 07:08
Hello,
So how do we migrate data to 2.0 ? I'm planning on experimenting production data on 2.0 but cbrestore looks incompatible, i couldn't find any documents on this, can you guide me please ?
Note that upgrade/rebalance isn't an option here, i need to insert data to new cb server
Best regards,

Online upgrade using rebalance will be fully supported from 1.8.0 or 1.8.1 GA to 2.0 GA.
In the mean time, with 2.0 beta, we have a new cluster wide backup restore available. here a blog that provides more details: http://blog.couchbase.com/lost-your-files-rm-rf-no-problem-you-have-backup
hope this helps.
I've upgraded from CB 2.0 DP4 to 2.0 beta, where cbbackup not work at all. I've wrote 2 simple apps, first gets all needed data through DP4 api and stores it in fome file. The second one uses new api lib and restores data from file. I think with 1.8 you can do same trick. Also you can reorganazie your data, if you need, to use views and other new features of 2.0.
