Oh, I am extremely sorry. I was confused when typing the issue. Please help
me in fixing the issue. Production1 is my old server. Production2 is my new
server. Typing here correctly. Ignore all previous one's.

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


The old 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
vmail at production1.baplc.com's password:
usage: doveadm [-Dv] [-f <formatter>] <command> [<args>]

  altmove      [-u <user>|-A] [-S <socket_path>] <search query>
  auth         [-a <auth socket path>] [-x <auth info>] <user> [<password>]
  config       [doveconf parameters]
  director     add|flush|map|remove|status
  dump         [-t <type>] <path>
  expunge      [-u <user>|-A] [-S <socket_path>] <search query>

  help         <cmd>
  import       [-u <user>|-A] [-S <socket_path>] <source mail location>
<dest parent mailbox> <search query>
  kick         [-a <anvil socket path>] [-f] <user mask>[|]<ip/bits>

  penalty      [-a <anvil socket path>] [<ip/bits>]
  purge        [-u <user>|-A] [-S <socket_path>]
  pw           [-l] [-p plaintext] [-r rounds] [-s scheme] [-u user] [-V]
  reload
  search       [-u <user>|-A] [-S <socket_path>] <search query>
  sis          deduplicate|find
  stop
  user         [-a <userdb socket path>] [-x <auth info>] <user mask> [...]
  who          [-a <anvil socket path>] [-1] [<user mask>] [<ip/bits>]
