| Will cloning any Unix/Linux(RHEL, AIX) server which has wmb installed in it to another data center work? |

Yes. No. Maybe?
define "cloning"
define "work"

say there is an AIX server on which wmq and wmb are installed and are currently operational. I clone it and install it on a different system altogether.
Now I get that I would have to re-configuring the connection channels, would I be able to connect remotely through a toolkit and create and deploy new flows?
I would like to know if that is at all possible and if yes, what are the complications I might face. |

In the time it takes to do the clone, you could have run the scripts you used to create the QMGR and the Broker and be done with it.
You do have those scripts don't you?
You could edit those scripts to change and Channel connection data before you go ahead.
You could do all sorts of things including taking a backup of the broker.
As for issues?.... How about licensing?
Are you going to switch off the old system once the new one is running? Do you have enough PVU's on the new system? etc etc etc

Every time you reinvent the wheel the more square it gets (anon). If in doubt think and investigate before you ask silly questions. |

So by "clone" you mean an OS level copy of the entre file system and configuration to make an exact, byte-level copy of the AIX OS and the LPAR(s) running on it on a separate piece of hardware running in a different data center?
Of course it won't work.
The other data center will have a different network configuration (at the very least the machine will be on a different subnet & network segment) so the first thing you'll need to do is go into the OS and start changing all the network settings. This assumes that the queue manager & broker names match the standards for the new data center, which best practice says they shouldn't. You'll then spend so much time fiddling round trying to get the machine to work that it would be faster and cleaner to do what my worthy associate suggests; rebuild from scripts.
The only thing worse would be "cloning" the file systems where WMB & MQ are installed, and mounting them on the new system. Which you'd never get working.
