I am about to move hosts for my website. I need to change the nameserver (Siteground -> Cloudflare) as well as edit the A-record so that it points to the new host (SG -> Cloudways).
Since I have never carried out a move like this before and my research has not shown anything yet, the question is which procedure is best so that there is as little downtime as possible.
Should I first move the nameserver while the A-record is still pointing to the old host and only direct the A-record to the new host when the nameserver has been propagated?
Or can I pre-configure the new nameserver with the new A-record and then carry out the move directly all together?
Or is there another better approach that I haven't thought of yet?
I have already reduced the TTL everywhere, so the records should be updated as fast as possible.
