the raster map format hasn't changed at all. If you have problems with
raster maps check the files. I can't find the "Fail of initial read of
compressedfile" error message anywhere- what specific 6.x version is
this?

the vector and sites formats *have* changed from GRASS 5; you will need
to run v.convert or v.convert.all, and v.in.sites or v.in.sites.all to
make them usable with GRASS 6.

GRASS 5.3 was a development version without release. If you are looking,
look for a package of GRASS 5.4.0. Or download the source code from the
"old versions" section of the GRASS download page compile it yourself:
  http://hamish.bowman.googlepages.com/debiangisfiles#compile
(that's for GRASS 6, but mostly the same. I have older instructions
buried somewhere if you find you really need them)

you can safely have two versions of GRASS installed at the same time.
(hell, I've got 7 different official versions installed right now)
