Need to change domain membership of SQL Server , what are the implications?

Hello there,

What are the implication of changing the domain membership of the SQL server?
Is SQL server tied up with hostname or FQDN of the server?
How will it impact the instances (Default) installed in the servers.

Regards and thanks

If the FQDN change, then you may need to check any connection strings in any apps or web sites that refer to it. Sometimes, it may just use the short server name rather than a FQDN.
The next major thing is that any permissions will change esp. if using Mixed Mode and using AD usernames for users to access the database. These will all need changing.

Double check the configuration for the services to see what account is being used for sql services it could be using a domain account.

Check the sql server's security settings for domain accounts.

You might want to make sure that your sql server is configured in mixed mode and that you have the sa password .......

This question has a lot of depends.
Depends of:
- The IP address will also change?
- The SQL Server, SQL Agent and SQL Browser services accounts are domain accounts?
- There are any SQL Server domain logins?
- It's a clustered instance?
- The machine name will be also changed?
(...) can't remember nothing else by now and more questions may be raised depending on your answers

What's need to be done:
- Update DNS
- Update SPN
