Moving from test server to production server

Moving from test server to production server

Can anyone help how I can quickly move updates on service catalog request template such as new fields, and new field and form rules from a test server to production server?

With the current state,if I spend 48 hours on changes for one request template on the TEST server, I have to use almost the same number of hours to move that new catalog to the PRODUCTION server.

I was used to a quick solution using Service-Now's "Update Set" but here with SDP, it's really taking a loooonnngg time.
