You will need to decrypt your disk before installing Lion.
The last time we tried this, not all the features of PGP worked under
Lion. If you tried to launch the Desktop app it would say "PGP Desktop
is not supported on this version of OS X." Through some command-line
hackery, it's possible to get it to re-encrypt. However, this is not
recommended by Symantec, and I wouldn't recommend you try it until
there's a supported release.
We do not know when Symantec plans to release a version of PGP Desktop
that is compatible with OS X Lion.
