repository migration (sidegrade)

[Marco Piovesana <pi...@esteco.com>]

Hi all,
I'm trying to sidegrade my repository from a SegmentNodeStore to a
DocumentNodeStore using the oak-upgrade module. At first, I couldn't run it
because of OAK-5591 <https://issues.apache.org/jira/browse/OAK-5591>. Then
I put all segment files within a folder called "*segmentstore*" and it
started, but it failed again saying that "*This combination of data- and
node-stores is not supported*". I tried with and without the
*copy-binaries* option
but nothing changes.
I double-checked the documentation here
<https://jackrabbit.apache.org/oak/docs/migration.html> and for what I can
understand it should work, am I wrong?

Marco.

Answering to my own question. If I specify the "*--src-fileblobstore*" of
my blob store then it works, I guess adding the folder "*segmentstore*"
messes things up. I do have another question though: if I try to copy the
binaries then the procedure fails saying:

Caused by: java.lang.IllegalArgumentException:

 If I remove the *copy-binaries* options it works fine. Is it because I
can't copy the binaries from a FileBlobStore into the Mongo NodeStore? Is
there a way to sidegrade the repository putting the binary store also in
Mongo?
