Need Help Changing Tubes in Mark III

[path09en]

Need to pick the brains of all the Mesa/Boogie experts:

I will be receiving a Mark III that has had 4x6L6s in its power section for almost 3 months, but with very little use. I want to change the outer tubes to EL34s.

Do I need to change out the two middle 6L6s with NEW 6L6s as well?

If so, should I just change ALL pre-amp and power tubes all together?

I would rather not change all the tubes, but if it is a MUST, then I will.

What ramifications should I expect in either case?

HELP!
