Archiving Data from Vantage 6.10.532

Because of the feeling that we get that the amount of data is slowing
Vantage down. I would like to ask if someone has experience in
archiving data from Vantage 6.10.532?

For example remove the first 2 (production) years towards an archive
database.

Opening overviews like packing-slips/shipments is taking longer and
longer.
