Transferring existing droplet to subdomain on another droplet
Hi, I have two droplets that are each currently accessed through their own domains (let's called them domainA and domainB). However, I would like to merge the domains so that the droplet accessed via domainB is a now accessed as a subdomain of domainA.
I created an A record for a subdomain for domainA, and when I navigate to subdomain.domainA.com it successfully takes me to the site hosted on domainB's droplet. However, the url in the browser changes to domainB.com instead of staying subdomain.domainA.com. What should I do to make sure the url displays correctly?
Additionally, I will likely keep domainB around for awhile in case old users try to return to it, but I would like it to redirect to subdomain.domainA.com. However I still want to keep the subdomain on a different droplet so I don't have to change all the db references and such in my code.
