Two Different Plesk Package Versions

[sparkybarkalot]

I upgraded Plesk and now "rpm qa psa" tells me I have two versions of psa.x86_64:

psa-9.5.2-cos5.build95100504.10
psa-9.0.1-cos5.build90090127.18

I need to remove 9.0.1 but it looks like that's going to remove a lot of dependencies that 9.5.2 requires. Do I have to "yum erase" both of them and install 9.5.2 or is there something less drastic, like some command to erase just the one specific version of a package and none of it's dependencies?

Thanks much for any help.
