Migration without chaos
The safest migration has a plan: data backup, testing on the new hosting account, e-mail and DNS configuration, SSL, a switch window and checks after delegation or record changes.
Maintenance after deployment
After migration, backups, application updates, PHP version control, e-mail checks, DNS verification and SSL certificate hygiene help keep the service stable.
Technical support when problems appear
A useful support request includes symptoms, domain, time of the issue, last change and examples of errors. It helps separate hosting, DNS, e-mail, application and external-integration causes faster.
