Database Migration issues to delevloper preview 3
we have a couchbase cluster (a smallish one with 4 nodes...) here running on version "ge4c8742".
Upgrading one node to developer preview breaks the cluster, partially.
The upgraded node is visible from the older siblings in the cluster but the upgraded node can't reach the cluster (says the gui)
Funny thing is the log is empty even with logging set log level to "debug" in the ini file
Even purging the upgraded node, incl. the database, and reinstalling does not change the behaviour.
Is there a migration path from prevois development version to the newset one?
Or ist it just my setup that is broken?
Or do we really have to copy the data record for record with a script via REST (or similar) from the old to a new cluster?
BTW, we are using the debian/ubuntu .deb packages.
