I have a server RH EL4 with MySQL run on it.

MySQL-shared-standard-5.0.22-0.rhel4.i386.rpm
MySQL-server-standard-5.0.22-0.rhel4.i386.rpm
MySQL-client-standard-5.0.22-0.rhel4.i386.rpm

Now we move to new server with newer version of RH. It's RedHat Enterprise Linux 5 and i can't find MySQL-shared-standard-5.0.22-0.rhel4.i386.rpm from Redhat website anymore so i have to install new packages from www.mysql.com but before i do that I want to know whether i can use these package below without any incompatible:

MySQL-client-community-5.1.30-0.rhel5.i386
MySQL-server-community-5.1.30-0.rhel5.i386
MySQL-shared-community-5.1.30-0.rhel5.i386

BTW, what is the difference between
MySQL-shared-community-5.1.30-0.rhel5.i386 and
MySQL-shared-compat-5.1.30-0.rhel5.i386

If anybody can help, i really appreciated. thank you.
