Hi everybody,
I have a situation that I wanted to know if it is possible to run orientdb v2.0.15 and v2.1.5 on same cluster or this may destroy the cluster?

the fact is that I have a cluster of 2.0.15 that I would like to upgrade but because doing it atomically would not be possible, I would like to upgrade nodes one by one. This will give me the best result but I'm not sure if this is something possible. Probably the guys with insights into between node messages know the answer the best.

regards,
Mohammad

Hi Mohammad,

this is strongly discouraged with 2.0, you could have big problems with this approach

Thanks

Luigi

Hi Luigi,
thanks for pointing it out, then I can only imagine that an upgrade would then need some off time.

thanks
