Bird on Ubuntu VM.

[David Petera]

Hi Mike,

there is no simple algorithm for converting the configuration from v1 to 
v2/v3, but the most important changes have been covered in this RIPE87 
talk by Maria: https://ripe87.ripe.net/archives/video/1135/

As for which version to choose:

The same configuration works (for most setups) with v2 and v3, so there 
is no difference in that.
BIRD v3 should be faster (since it's multi-threaded) and more 
future-proof, however we released the stable version just last month so 
it might be more prone to bugs.
BIRD v2 is single-threaded implementation, but much more tested by real 
world situations, so you can expect it to be more stable.

I would start with v3, as the setup from v1 is unlikely to encounter any 
niche corner cases.
If any problems arise, you can simply switch to the latest v2 (currently 
2.16) using the same configuration.

You can post specific questions about parts of your configuration to 
this list and somebody is sure to help you.

Hope this helps!
David
