generally, you would export both keys

Arnold, You mean to say I can export the keys from old machine and put it in one folder and copy those into the new machine. I import the keys to the PGP tools in the new server right?

It wont get any impact to the exisiting machine right. Becoz currently the old machine is the live production server.  Please advise.

Thanks

You have a general description, at times the files containing the keys, keychain, ....... Are in a specific location for some ....

If you could tell us the PGP software you are using currently it would help us guide you in the proper steps.

OPENPGP Studio tool
