You can safely remove everything from the previous installation - I'm
supposing, your 8.2.x data directory is totally separate?

There is no hidden connection between both data directories. You dumped
everything into a file, so everything was in that file, then you
restored to 8.2.x, so everything is in 8.2.x now.

HTH,

Tino.
