Hi I need to migrate 10 websites from a server to another, including name server, email and DNS configuration (5 Wordpress sites, 1 custom php application, 4 simple domain redirects).
The old server is debian with Sirectadmin. Now we have a problem with httpd (need to be restarted-reinstalled) and I cannot show you the website. So you should fix it before migration.
You should move those website to new hosting (Wpengine for Wordpress websites), configure mail dns records to work with google app and change domain nameservers to point to a managed dns service (eg. [url removed, login to view])
The custom PHP application has to be moved to a separate hosting, while the redirects can be managed simply configuring the DNS.
I will pay a first milestone when 5 websites are migrated.
