Hi Waseem_a,

Yes this is correct, if you remove the keys used by server 'B' before they have the key from server 'A' you will loose communication with server 'B' clients. do not remove the keys.

What you are doing is covered by this article:

Re: ePO Migration

Hi Waseem_a,

You cant migrate multiple ePO servers all at once, you will have to migrate them one at a time I'm afraid.

What is going to be a key point in that activity is the SQL dB, it will become vary large very fast. A basic approach to the dB Growth would be to add together the current ePO dB sizes;

                  svr1dB + svr2dB + etc = "Master Server dB"

It is a crude and basic approach , but so long as the process does not run out of space, you can always 'recycle/reclaim' the hdd space should you have far to much once the migration is complete.
(Easier to reclaim HDD space then to deal with issues that arise when you run out of space)

The following should help you in that action:

  • How to migrate policies and systems from one ePO server to another
    Technical Articles ID: KB88822
  • How to migrate ePO from a 32-bit system to a 64-bit system (or to a different installation path)
    Technical Articles ID: KB71078
  • Statement regarding the migration of managed encrypted systems from one ePolicy Orchestrator server to another
    Technical Articles ID: KB83186

If you have Drive encryption review the third article (KB83186) above first and action is needed.

Re: ePO Migration

Hi,

I have migrated one ePO by importing the keys from the old ePO server (B) to the new ePO server (A). At this point if I remove the keys that were used to communicate to agents in server B and import new keys of a different ePO server (C). Then I will loose communication of the agents that are communicating to the ePO with server B keys. 

 

So I believe that the only way to proceed with the other ePO servers is exporting the systems and then importing them to the new one.

Waseem,

When I did it, I created the new ePO and DB server, synched ePO to AD, then exported appropriate client tasks, policies assignments, keys and server tasks, then imported those onto the new server.  I then started reassigning/moving  ~ 500 systems a day from the other servers to the new server.  I kept it to 500/day so the server wouldn't get too busy.  It took about three weeks to move the systems and a week to set up the new servers for ~ 5k systems.

HTH,
