Migrate OH DB4O to OH2?

achileos · February 24, 2017, 5:07pm

Hello there,

Quite some time since I’ve been last active here . Currently on holiday and trying to migrate my beloved OH1 instance to OH2 and facing a big isssue :

How on earth can I keep my db4o data in OH2 ? I’m fine with migrating to another service, but anyone got his data migrated ? Got almost 3 Years of data there.

Should I stick to OH1 ?

Thanks !

I was able to copy over the openHAB 1 binding and db and use them in openHAB 2.

Not sharing the luck … Maybe I missed something else :
