Issue Migration Manager ERROR! does not correctly recognize the Plesk version

[Noct]

I have two vps, both with:
Plesk Onyx Version 17.8.11 Update #45
When i try to migrate, seems this error:
"Version of Plesk on the target server (17.5.3) is lower than version of Plesk on the source server 'source' (17.8.11). Migration to lower version of Plesk is not supported by migration tool."

Note:
The target server has initially installed version 17.5.3 and then updated to the current version. 17.8.11 #45
I do not understand why it keeps giving the same error, if the two already have the current version...
I tried to reinstall the extension ... but the error persists

Run command

# plesk version

on both servers, please.

Try to fix it with

# plesk installer --select-release-current --reinstall-patch --upgrade-installed-components
# plesk repair installation
