Migration Manager / Agent mismatch

[colinjack]

I have a 10.3.1 Panel running on a server that I want to migrate to a newer server.
On the new server I have also installed 10.3.1 and ensured it is all up to date.

I then went into the Migration Manager (on the new server) and clicked 'synchronize' to download the latest Migration Agent. I copied this to the old/source server and installed it.

Problem when I try and migrate is that the new (target) server says the agent is older than the installed migration agent (even though I used the new server to download the correct version!!).

"Error: The version of Plesk Migration Agent running on the remote host is older than the version of Plesk Migration Manager being currently used. Please install Plesk Migration Manager components of the same version."

Looks like a versioning problem with 10.3.1 but what is the solution?

Any Parallels Tech staff monitoring this forum?

I advise you this article for more detailed search of the reason of this error - http://kb.odin.com/en/9679

I have already read that article.

The problem is that the latest Migration Agent is version 10.300.4241.27730 dated the 12th August. The Migration Manager is up to date but here is the problem:

2: Info 31/08/2011 22:21:23.656 : CrossSysAgent::connectToWindowsHost Try connect to (x.x.x.x) as Windows host via Remoting

It looks like I need to match the versions. I even tried installing the agent in the migration manager folder but no better.

 

[IgorG]

Try to install the same Migration Agent from http://www.parallels.com/download/plesk10.3/ on both servers manually.

 

[colinjack]

Sorry, bit of a lame question, but how do I manually install it on the target server - just drop it in the migration manager folder?

I can install it on the source server from the msi easily enough.

 

[IgorG]

You haven't admin's access to destination server?

 

[colinjack]

Yes - I have admin access to both servers.

I have been installing the agent on the source (old) server using the installer (plesk-migration-agent.msi).
I haven't been installing it on the new target/receiving server because I am running the Migration Manager from the GUI.
Do I need to install the agent on the new server using the installer too?

 

[IgorG]

Yes, install the same agent on both servers.

 

[colinjack]

No better:

"Error: The version of Plesk Migration Agent running on the remote host is older than the version of Plesk Migration Manager being currently used. Please install Plesk Migration Manager components of the same version."

I have installed on both servers but:

28: Debug 01/09/2011 10:54:49.823 : CrossSysAgent::connectToWindowsHost remote migrator core version (10.300.4156.24194)

Looks like it isn't seeing the correct version? If I click the 'Advanced' button on the source server it says 10.300.4156.24194 but if I look at WINAgentMng.exe properties in /PleskMigrationAgent it says 10.300.4241.27730

 

[MargaritaK]

check your migration.log and if you'll see the next string:
CrossSysAgent::CheckVersion. remoteVersion (0.0), localVersion (10.300.4198.28991)
try use this article http://kb.odin.com/8193

 

[colinjack]

Thanks for the tip. I do have:

2328: Info 01/09/2011 13:03:42.270 : CrossSysAgent::CheckVersion. remoteVersion (0.0), localVersion (10.300.4198.28991

I checked the KB article and the WINAgentMng.exe.config file on the source server does have the correct IP:

"If a specific IP address is set for the IP address key in the WINAgentMng.exe.config file, make sure that it is a valid address and that it is the same as the address entered in Source host field on the Remote Host Connection Setup screen during Migration setup. If it is different, either set the value of the key to "0.0.0.0" or remove the key from the WINAgentMng.exe.config file altogether."

Migration still failing but I think the error message is incorrect - I think we are getting closer to the real problem here but haven't solved it!

The Migration.log says

3812: Info 08/09/2011 12:29:03.401 : CrossSysAgent::CheckVersion. remoteVersion (10.300.4156.24194), localVersion (10.300.4156.22954)

So it appears to be a versioning problem. Although, if I'm interpreting this information correctly and the version numbers mean anything, the error is actually the opposite to what is being reported.

The remote (source) server has a later version (24194) than the local (destination) server (22954)

 

[colinjack]

Are you using NAT? I eventually found the problem had nothing to do with versioning!

 

[Mike Legg]

Thanks for the tip, but no, we're not using NAT. Nothing is enabled under the "Routing and Remote Access" Snap In.

 

[colinjack]

Are the two servers on the same subnet?

 

[Mike Legg]

Are the two servers on the same subnet?

No they're in completely different IP ranges (different data centre)

 

[colinjack]

That's your problem (as was ours). I eventually solved it by creating a VPN between the two datacentres and using the non-routable addresses.

I'll give that a go and see if it helps. Thanks for the tip.

This shouldn't really be necessary though should it? If it is, the documentation has a glaring ommission
