I've removed (for now) the large strings and now the upgrade has started.

I have to say, it's a lot slower than I anticipated but its running :)

Hi Tomek,

We are aiming at having a cluster of Oaks . I'll see if I can find the 
offending large string.

Hi Robert,

I think the quoted exception may be caused by some long string stored in the 
Jackrabbit 2 repository. In MongoMK all the strings are inlined in the Mongo 
documents, while the binaries are extracted to the blob store. Therefore, 
string properties longer than ~15MB are not supported. It’s a hard limit of the 
Mongo implementation itself.

Migrating this repository may require changing the repository structure - the 
large properties type should be changed from STRING to BINARY.

As Torgeir noticed, SegmentMK doesn’t have such constraints. If you don’t need 
to create a cluster of Oaks, then SegmentMK is a better choice anyway.
