2.3 vs 2.4 compatibility

Hi!

Are persistent storage compatible between 2.3 and 2.4 ? I upgraded to 
2.4 and got a lot of exceptions at startup, when I deleted all the 
persistence files and restarted everything worked fine, no big deal, 
just wanted to know if it should work with 2.3 persistence files and 
upgrade to 2.4 or if it's not expected to work.

I made a backup of the files before I deleted them so I guess I can 
repeat it again, I will have a look at it.

Hi,

It should work and data from 2.3 should be loaded by 2.4. Could you please
share details?

Do you have logs, and entries saved in persistent store?

Sincerely,
Dmitriy Pavlov
