Migrate to a new Patch Manager server - options?

My current Patch Manager server has been misbehaving for past several months to the point where I would like to build a new one from scratch, and migrate over any custom patches I've created.  Can anyone advise what my options are for migrating Patch Manager services to a new server build?  I don't need patch history or anything like that, so I'm fine with doing a fresh build, and resynchronizing everything.  But i would like to bring over my custom packages.  Thanks for any advice/leads/tips/experiences/warnings...
