After having moved servers just recently, Manuel Lemos has a few helpful hints for anyone out there considering a web site/web server move in the near future:
Despite the benefits of migrating to a better server, the actual migration is a complicated process that can fail in so many ways that I thought it would be a good idea to share what you need to be concerned if you need to migrate your servers too. You need to go through several steps that need to be done in the right order to prevent major headaches.
Here's his ten steps/recommendations of things to keep an eye on during the move:
- Prepare your DNS
- Setup the new server
- Tune the server file system for performance and integrity
- Install the base applications
- Initial data migration
- Put the old server in migration mode
- Bring your new server to life
- Double check your server security
- Epilogue (the final miscellaneous startup/setup items)
- The forgotten step that you remembered
