Many members of DELOC have their CCDW, and then applied for their LTCF in PA. A requirement for an non-resident LTCF is a license/permit from their home State.
So if you're moving to PA, I believe you'd need a LTCF from PA. I don't think your CCDW from DE would be good in PA, although it should let you easily apply for a LTCF since you'll be a "new" resident there.
The good news is that PA is a "shall issue" State (unlike DE)....
