Re: 200D to 200E - Easiest way to migrate / upgrade ?
your are right, you won't be able import your 200D config out-of-the-box.
But you have a couple of options:
- Use the FortiConverter Service (one-time offer since E-Series) for your new 200E to get the .conf file migrated if you want to keep your setup the same. You may also buy the whole software tool if you have that use-case more often.
- edit the whole thing yourself using the default config and match the interfaces, hardware, software-switches etc. This might be time consuming.
- I like to use a migration as an opportunity to clean up a little and straighten up the whole setup (since you do a downtime anyway aren't you?) - you can copy the most obnoxious part of your config like objects and default settings (might need to edit some interface names) and do a clean re-build of things you might are happy to get cleaned up. Might throw in some scripting here and there.
