I have the following issue with my Databases:
I have 1 domain registered with DH (domain A) and 2 domains hosted with DH but registered elsewhere (domains B and C).
All my databases have their hostnames at domain A (panel->Manage account->Databases->Hostname(for each DB)).
At the same time all these databases are actually hosted at domains B and C (panel->MySQL databases->name of MySQL server->Hostname(these are all interchangeable)).
The latter hostnames in mysql subdomains (mysql.domain BorC) are “real” which means that all my web applications on domains B and C are actually pointing to these hostnames (in wp_config.php).
My domain registration for domain A will expire soon and I don’t want to renew it. Instead I registered a new domain (domain D) via DH and hosted it here.
What actions should be performed (if any) to change the hostname of my databases from domain A to domain D before registration of domain A expires?
What are the risks?
Thank you very much!
