Issue Directadmin to Plesk Migration problem

[simoncsc]

Server operating system version

CentOS Linux release 8.5.2111

Plesk version and microupdate number

Plesk Obsidian v18.0.59_build1800240226.11 os_Debian 12.0

hello

My Directadmin OS version is "CentOS Linux release 8.5.2111"
I can ssh to my Directadmin server via putty with root account

Now I am tring to migrate my current Directadmin to Plesk via plesk tools "Migration & Transfer Manager", but I got below error before it starts:

Failed to deploy Python on source server
Cause: Error while connecting to the the source server 'directadmin' (IP Address) at 'IP Address' by SSH as 'root': Unable to connect to 'IP Address' by SSH: [Errno None] Unable to connect to port 14686 on IP Address.
Ensure that the server is up and there are no firewall rules that may block SSH connections to the server,
then restart migration.
That is a critical error, migration was stopped.

Thank you for letting us know, but in this case it seems to be an issue on the source server or its firewall that does not let SSH through.

But I can login to my server via putty with root ID

1. Connect to the server via SSH


2. Edit the following file on the target(Plesk) server:


/usr/local/psa/admin/plib/modules/panel-migrator/backend/lib/python/parallels/plesk/source/custom/actions/deploy_migrator_python.py


Append the (OSName.OS_CLOUDLINUX, '8'): 'PMM_0.1.11', line as follows:

redhat_oses = {
(OSName.OS_CENTOS, '5'): 'PMM_0.1.10',
(OSName.OS_CENTOS, '6'): 'PMM_0.1.11',
(OSName.OS_CENTOS, '7'): 'PMM_0.1.11',
(OSName.OS_CENTOS, '8'): 'PMM_0.1.11',
(OSName.OS_RHEL, '5'): 'PMM_0.1.10',
(OSName.OS_RHEL, '6'): 'PMM_0.1.11',
(OSName.OS_RHEL, '7'): 'PMM_0.1.11',
(OSName.OS_RHEL, '8'): 'PMM_0.1.11',
(OSName.OS_CLOUDLINUX, '5'): 'PMM_0.1.10',
(OSName.OS_CLOUDLINUX, '6'): 'PMM_0.1.11',
(OSName.OS_CLOUDLINUX, '7'): 'PMM_0.1.11',
(OSName.OS_CLOUDLINUX, '8'): 'PMM_0.1.11',
}

3. Re-Run the migration.



In your case make sure that the RHEL 8 line exists.

Still same issue after added the line.

After added the line, the error message is little diffrence before

You mentioned that you can login to the source with PuTTY, but did you try to SSH into your source server from the target server manually, so that you can verify that basically a root login from the target to source via SSH is possible?
