safe to dist-upgrade?

[maverick0815]

I have the alpha 2.37 installed and today I tried an
apt-get update
apt-get dist-upgrade
so far I had the avenard repo activated. I now noticed that there are a bunch of updates including mythtv 0.22
is it safe to perform the upgrade, or am I going to face some major issues with that? The last time I did this, around the time the beta came out, it really screwed up my system.
I had to recreate the mythtv database and such...so can I do this, or will there be a "safe" upgrade path from the alpha to the beta?
