Data and programs can always get corrupted or be accidentally erased. before you ever do a major upgrade, back up all of your data.

Thanks for your reply
your saying is true and I agree, but I want to know about Debian upgrade and upgrading mysql.
thanks in advanced

Follow the Lenny release notes and check the BTS for anything mysql related and you should be fine.
