Should be fairly simple.

1)  Archive all your old stuff.  Backups == life preserver.
2)  Remove _all_ your old stuff, but not the backups. :)
3)  Uncompress, untar, cd snort-2.0.3, ./configure <options> , make, make
install.
4)  cp etc/* to <snort_config_dir>
5)  cp rules/* to <snort_rules_dir>
6)  Modify the new snort.conf to reflect your network (HOME_NET, etc.)
7)  Restart with the new version.

Now, one thing that you may need to do is update your DB schema.
Depending on the changes, between schemas it could be simple or complex.
IIRC, 1.06 is the current schema and I don't think it's changed from
before Snort 1.8.6.  If that's the case, you're good.  If not, you may
have to drop all your tables/data and recreate (the simple way), or
actually modify the tables to the new schema (icky).

Cheers!
