Merge Tags at file level

Is it possible to merge history (within the same dataset) by adding new hdb3 file to the data set?

I see tags can be merged at the Views level which is a great option in many scenarios:

I have a large amount of historic data that I migrated into an instance of Canary on a dev server, and now I would like to transfer those hdb3 files to production which already has live data flowing in (same tags).

Is it as simple as choosing a cutover date, deleting any overlapping hdb3 files, and then just placing them all in the same folder?
