Migration from one server to 2 new servers

[Kishore Potnuru]

I am executing the command from the new server. I was executing the command
from production2 server only. It has the backup option, but whereas
production1 doesn't have it. Though I am executing from production2, I am
seeing the below error. Is it becasue production1 server doesn't have that
option? Please let me know, if it is confusing.


The old version is:
====================
[root at production2 ~]# dovecot --version
2.2.36 (1f10bfa63)


The New version is :
======================
[root at production1 ~]# dovecot --version
2.0.9


I have executed the command from the new server:



=================================
[root at production2 test.org.com]# doveadm backup -R -u kishore at test.org.com
remote:vmail at production1.baplc.com
