Possible: sure. Each Debian distribution supports running on kernel of

previous version.



Wise? You generally have less than a year to migrate. It would probably

be a good idea to ask them when will they provide you with a newer

kernel to make a more informed decision.

This looks fine. Naturally it would help if you can test the upgrade on

a similar server.

I think the best thing to do is to ask your VPS provider if they support this upgrade, perhaps they will invite you to reimage your VPS using Lenny(not an option for all the services already running on your VPS).

I have already use Lenny under OpenVZ(is the opensource option for Virtuozzo) without any issue, although I haven't upgraded Etch to Lenny under OpenVZ.
