<title>Re: dhcpd 4.2.4 vs 4.3.5</title>
<span style=" font-family:'Courier New'; font-size: 9pt;">I should
have added - I've read the release notes [mainly searching for
"peer"], and there's not much mentioned about changes in peer
communications or the peer underpinnings - so I'd *guess*
they'll talk fine - but having someone with some real knowledge
weigh in would be a lot more helpful in making me feel fairly
confident it will.<br>
<br>
[I just don't want to turn off a 4.2.4 and bring up a 4.3.5 and
have it make a hash of things, so it's quite difficult to go
back to 4.2.4, and suddenly I don't have any working DHCP
servers!]<br>
<br>
Again, thanks for any light someone might shed on this!<br>

<br>
Should failover peers running 4.2.4 talk to another peer
running 4.3.5 properly?<br>
Or are there differences large enough between the two
versions to prevent them from working as a pair?<br>
<br>
[Reason - I'm upgrading a pair of 4.2.4's to 4.3.5 - and
moving one of the pair to 4.3.5 and then the other also
to 4.3.5 seems like a very nice way to manage the
upgrade. But they'll have to work together well to do it
this way.]<br>
