adding a older vault version visibility when running newer PDM version

Hi all,

We are currently using Solidworks PDM 2018 which has only one vault .

We are about to update to Solidworks PDM 2019 and I would like to know if I can still have visibility to that vault once we upgrade (we are not migrating the data for  now, that is why I still need visibility to it).

I have tested it in my computer but it has failed to work.

Has anyone has any experience on this subject?
