install bigfix server on existing database

Hello,
can i install bigfix server on existing database of the old one?
using the same masthead of the old one.

You don’t say whether this is the same version of an upgrade, but my expectation is probably not, unless you have copies of everything you would have if following the recommended backup/restore process

Take a look at this doc as well…
