A switch doesn't keep archived (older) versions of vlan.dat - either in volatile (RAM) or non-volatile (flash) memory on its own accord.
If you had a backed up copy offline, that could be used. Otherwise you are stuck with recreating the VLANs manually.

If it was overwritten then it's gone.
If you want a particular switch to operate with an exclusive set of VLAN tables, then configure this as transparent.
