• Debian 11 is approaching its end-of-life (vendor EOL date - August 31, 2026). Plesk Obsidian 18.0.80 will be the last release to support it.
    If you are running Plesk Obsidian on Debian 11, we recommend you upgrade those servers to Debian 12 using our dist-upgrade tool.
  • We plan to deprecate and remove the support for XML RPC protocol versions earlier than 1.6.9.1 in Plesk Obsidian 18.0.82. We strongly recommend that you update all existing integrations using earlier versions of the XML RPC protocol to comply with the version 1.6.9.1 specification.

Plesk 8.3 for Windows: migration issue

SashaL

New Pleskian
Hello All,

We're to migrate from 8.3.0.1 Update 080228.13 to v11.5.30_build20130801.15 os_Windows 2008/2012
PMM was setup on the source host, PMA is running with the default settings (http/6489/WinAgentURI)

At the Migration & Transfer Manager I see this error:

Error: Connection to host is not available or migration agent is not running on the source host


I checked http://kb.parallels.com/en/1432 and can connect to \\src.ip\c$ with the valid login/pass.

Next, I checked http://kb.parallels.com/en/9679 and find this error in log files:

Tcp channel protocol violation: expecting preamble


Please help.

p.s. I tried to attach log files but it looks this part is broken on this forum: just white window after I press 'manage attachments'. Tried FF and Chrome Linux, FF Windows.

Please let me know if you need complete logs and I'll paste them here.
