Need to access the impact of changing server IP address

  • we plan to move our sql server from one place to another place. It's IP has to been changed, yet the hostname can be kept. I need to access the possible impact of this move. Our application server query the datababase by server name. Apart from changing the DNS, what else I have to pay attention ?

  • if you use hostname in the connection strings, than all you have to do is update DNS.  Just make sure you identify all connection strings DSN's etc.

  • thanks Vik.

  • Don't forget to go into SQL ServerConfiguration manager and make sure the "Listen on" settings under protocols, tcpip, properties reflect the proper IP address(es).  Should be fine for most folks, but in our case we had bound SQL to only one of the network cards in the server and when changing the IP address, we had to change these settings.

  • It will also depend on if you are using IP address for your link server.  Note all other machines Host files will need to be updated to the new address also.

    Also, if your users/developers have the IP address hard coded for SQL Server Management Studio, then they will have to change also.

    Good Luck

  • Since Windows caches DNS information you may have to resort to some specific windows level actions on your machines in addition to the abovementioned items.

    For the clients this would be:

    IPCONFIG /FLUSHDNS

    For the SQL Servers this would be:

    IPCONFIG /RENEW

    IPCONFIG /REGISTERDNS
