Is it safe / good to upgrade old vB to current beta?

[ManoOne]

The title says it all.

I have a community of 6000 members / 36000 messages and I was wondering if I should upgrade from the old vB to the current beta (5) of vB 2.0?

Is it safe, and by this I mean is it stable and will I have major problems?

I talked to a friend (who is also a friend of the vB team ) and he is waiting for the RELEASE to upgrade...

I'm looking forward to see your input and suggestions,
Best regards,

The release is getting very close now. I'd be inclined to wait.
