<p>Hi Mike,<br>
<br>
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:
<a class="moz-txt-link-freetext" href="https://ripe87.ripe.net/archives/video/1135/">https://ripe87.ripe.net/archives/video/1135/</a><br>
<br>
As for which version to choose:<br>
<br>
The same configuration works (for most setups) with v2 and v3, so
there is no difference in that.<br>
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.<br>
BIRD v2 is single-threaded implementation, but much more tested by
real world situations, so you can expect it to be more stable.<br>
<br>
I would start with v3, as the setup from v1 is unlikely to
encounter any niche corner cases. <br>
If any problems arise, you can simply switch to the latest v2
(currently 2.16) using the same configuration.<br>
<br>
You can post specific questions about parts of your configuration
to this list and somebody is sure to help you.<br>
<br>
Hope this helps!<br>
David<br>

<div>What about upgrade? to 2.x or 3.x?</div>
<div>Do you have any guide on how to upgrade configuration from
1.6 to a higher version?</div>

<p>I currently have 2 servers Dell R310 with Bird 1.6 on
Ubuntu
(Active/Passive), one full BGP table and one IX,
traffic around 400Mbps,
simple BGP routing. I also have an HA cluster built on
ESXi and I wonder
if it would be a good idea to run BIRD (maybe
2.0/3.0?) on a VM (Ubuntu)
on this ESXi HA cluster. What are your experiences
with this, what are
the limitations and recommendations?</p>

<p>It will run, BIRD just works if you give enough memory
to hold the
tables. I have recently encountered some performance
problems with
Netlink when trying to feed 10+ container nodes with
full BGP at once,
but ESXi is a full virtualization, so no problem there.</p>
<p>And please upgrade from 1.6, that’s out of support for
more than a
year already.</p>
<p>Have a nice day!<br>
