The easiest way to switch from MFC (or any other systems is to do the
a) add boost serialization to your code.
b) when you open an archive - currently MFC, use code like the following:
read the first part of the stream
if doesn't contain a boost serialization signature
invoke MFC de-serialization
invoke boost de-serialization.
c) when you save an archive - just invoke boost serialization.
In this way, all your old files will be compatible and will gradually be
converted to the new system. The new archives can use all the new
facilities without compromise.
This is much easier, and forward looking than trying to adapt to an old
format wich likely isn't rich enough to support the new facilities.
