No.
Tear down an existing BB server is not as easy as it seems.
I don't buy that. Converting a BB server to Hobbit requires you to do two (maybe three) things:
- Move the RRD files around; there's a script included with Hobbit which takes care of that. Takes a few minutes at most.
- Convert your alert configuration from BB to Hobbit. Even for a moderately complex alert setup, I would guess you could do it in a day or two (can be done in advance).
- Server-side scripts may need a bit of tweaking, but for the most part they should work if you enable the compatibility module to save status logs and disable-files.
The logfiles are compatible between BB and Hobbit. The bb-hosts file is backward compatible so you can copy it from BB to Hobbit (not the other way around). The client configuration is different, but that doesn't matter when we're discussing the server migration.
So I disagree with your premise that migrating a server from BB to Hobbit is difficult. It is a lot more difficult to make the Hobbit clients compatible with a BB server. E.g. there is no way you can get a BB server to push the configuration to a Hobbit client without re-implementing parts of the Hobbit server in the BB network daemon.
