Migration Manager doesn't connect to agent.

Hello,

I'm trying to migrate from a Windows Server running Plesk 7.6 to another with Plesk 8.1. Everything is working properly, file and printer sharing installed on both, firewall correctly configured (even a port scan says it is so...).

On the Plesk destination server, I get the following error from the Migration.Log file:

Also, I get the same error even if I try to use the HTTP channel. (I posted my last attempt using TCP). Of course, I always configure the same channel on both the agent and the destination server.

But anyways, the error really looks like I'm missing a software component:

System.ComponentModel.Win32Exception: No network provider accepted the given network path

.

Anyone has an idea what's wrong/missing?

Hello,

Please, try to migrate using IP address instead of host name. If this will fail try to connect from the Plesk server to the share folder on the remote server with the following path \\XXX.XXX.XXX.XXX\ADMIN$ (replace XXX.XXX.XXX.XXX with the actual IP address of your remote server). If connection failed you should test necessary services on both servers, availability of system shares on remote server like ADMIN$, c$, etc.
If all settings are OK please send request to SWsoft support, or contact me with e-mail and we'll examine your sitaution closely.

Thanks.

Well, it seems like this kind of URI isn't expected by the piece of software that initiate the connection. Here's what I get following your suggestion:

Debug	03/02/2007 10:08:37 : Start migrmng execution in --deploy-scout mode
Debug	03/02/2007 10:08:37 : System.UriFormatException: Invalid URI: The format of the URI could not be determined.
   at System.Uri.Parse()
   at System.Uri..ctor(String uriString, Boolean dontEscape)
   at System.Uri..ctor(String uriString)
   at System.UriBuilder.get_Uri()
   at migrmng.App.ExtractConnectionParameters(CmdArgsParser parser)
   at migrmng.App.Main(String[] args)
Debug	03/02/2007 10:08:37 : migrmng exits with code -1
Debug	03/02/2007 10:08:38 : Unload domain.

But the services and the share are available, indeed. The results of a "net share" :

C:\Documents and Settings\Administrator>net share

Share name   Resource                        Remark

-------------------------------------------------------------------------------
IPC$                                         Remote IPC
ADMIN$       C:\WINDOWS                      Remote Admin
D$           D:\                             Default share
C$           C:\                             Default share
The command completed successfully.

I got the solution to my problem though. I will post it later: I must do some work now.

Everything looks alright now: we have successfully moved 4 domains. But the real big migration (70+ domains) has yet to come.

The problem I had was that the destination server had one of the network interfaces configured with an IP adress on the local subnet of the source server. But the machines weren't on the same LAN during my tests.
I noticed the "forgotten ip", one of many for that interface, when I used Wireshark and saw outgoing ARP requests for the source server's IP.

I can't believe I didn't try Wireshark before. What a waste of time...
