Cannot Migrate from Plesk Windows 10.x to 12.x

[HoracioS]

I received the following error when trying to migrate from Plesk 10.0.18 to 12.5:

On the destination server I can see on the log:
[INFO] START: Initiate callback from source server
[INFO] Deploy and start panel migrator transfer agent at 'xxx.x.xxx.xx'
[INFO] FINISH: Initiate callback from source server
[INFO] START: Check if migration list file already exists
[INFO] FINISH: Check if migration list file already exists
[INFO] START: Check migrator updates

[INFO] START: Check connections
[ERROR] Failed to connect to the source server 'source' (xxx.x.xxx.xx) by Plesk API: <urlopen error [Errno 8] _ssl.c:504: EOF occurred in violation of protocol>

Both FW are disabled.
I tried to start manually Transfer Agent on the source server and got this error:

C:\panel_migrator\panel-transfer-agent>[INFO] Start Parallels Panel Transfer agent

Please help!

Source Plesk server should be available by Plesk API with HTTPS protocol from target Plesk server.
Make sure that the following URL is available from the target server: https://<source-ip>:8443/enterprise/control/agent.php

Thank you Alexey, but this is the problem. https://<source-ip>:8443 from outside is not working (the fw is turned off) but works from the desktop! Because of this I want to migrate the Plesk.

Plesk Migrator requires Plesk API on the source server to work.
Is it available by HTTP, not HTTPS, from outside, e.g. http://<source-ip>:8880/enterprise/control/agent.php ?

I received the following message when trying http://<source-ip>:8880/enterprise/control/agent.php

Thank you Alexey, but this is the problem. https://<source-ip>:8443 from outside is not working (the fw is turned off) but works from the desktop! Because of this I want to migrate the Plesk.

By default Plesk Migrator use port 8443 and HTTPS to connect source Plesk XML-RPC API. There is ability to customize Plesk API url, but it is available only via CLI.

I received the following message when trying http://<source-ip>:8880/enterprise/control/agent.php

Looks like Plesk API available by http://<source-ip>:8880. So, you need to do following:

• Start migration via GUI
• When it fail, look for just created migration session in /usr/local/psa/var/modules/panel-migrator/sessions/ (session directory will be named YYYYMMDDHHIISS)
• Open file <PLESK_DATA_DIRECTORY>/var/modules/panel-migrator/sessions/YYYYMMDDHHIISS/config.ini (PLESK_DATA_DIRECTORY could be retrieved from registry: reg query "HKLM\SOFTWARE\Plesk\PSA Config\Config" /v PRODUCT_DATA_D /reg:32) and append following line into section [source]: plesk-url = "http://<source-ip>:8880/enterprise/control/agent.php"
• As a result section [source] in config file should looks like:

[source]
ip = "<source-ip>"
plesk-url = "http://<source-ip>:8880/enterprise/control/agent.php"
os = "unix"
...

After that you can continue migration via GUI in scope of the same migration session.
