Migration failed: Unable to create dump

[maddes]

Hi,

We are trying to migrate from Plesk 8.6 to Plesk 10.4.4 and we keep getting the following error in psadump.log:

I've searched through the forums and can't find anything that relates to this issue. What could the problem be and does anyone have any ideas on how we can fix it?

Many thanks

I am unable to migrate as well after succesfully migrating 100 domains......
The report_pmm_logs.php doesn't give any output....

We're in the middle of a bulk migration...
After about 100 domains it stopped working....

We still need to migrate about 40 domains....

Why isn't there any response?

 

[Bevan]

The report_pmm_logs.php doesn't give any output....

If I understand that script correctly it only creates any output if something fails. The result is dropped in a file named PMM-logs.zip in the current directory.

What can i do???

 

[Frater]

I wish I knew...

We have to pay each month for a server because we suddenly can't migrate domains anymore...
Most probable due to one of the infamous micro-updates....

 

[nocrash]

same line errors like maddes in the psdump.log .

the error protocol in the frontend just said

<?xml version="1.0" encoding="UTF-8"?>
<execution-result status="error" log-location="/usr/local/psa/PMM/rsessions/20120126093759719/migration.result">

</message>
</execution-result>

regardless of migration one or more domains from Plesk 9.5.4 (SLES 10.1) to 10.4.4 Update #13 (OSS 11.4), both 64 bit.

 

[Frater]

Come on Parallels!

This is a serious issue and there's not even attempt to get it fixed.

Plesk-Plesk Migration isn't something that's being done by many users but it is something we should be able to rely on.
Generic (non-plesk) stuff is something I could troubleshoot, but this isn't.
Especially because I'm not owning the original Plesk server and I have to rely on a third party for this.

The only thing I can do right now is to ask them each week if they're able to migrate a domain in the hope some micro-update fixed it. I wish this micro-update wasn't turned on at all... I don't know why it happens.

We need to transfer only 1 domain from a Plesk 8.5 server and about 50 from a 9.5 server.

Tell us at least what we can check.

Why you do not ask free migration assistance here - http://www.parallels.com/support/plesk/free10assistance_toc/ ?

Igor,

I followed your suggestion, I got free migration assistence and it seems the issue is now resolved.
I'm saying "it seems" as I'm not the admin of the source server and can't initiate the migration myself.

The migration engine is dependent of perl.

For my SMTP-proxy (ASSP) I needed to upgrade my perl installation in the past.
It turned out the DBD::mysql module was missing from this Perl.5.14.2 installation and couldn't be added because it failed to compile. It failed to compile because my CentOS was missing the mysql-devel installation.

After installing mysql-devel with the command:

yum install mysql-devel.x86_64

I was able to install DBD::mysql

perl -MCPAN -e 'install DBD::mysql'

This was however only half the issue.
The support team discovered a problem which they reported to the development team.
The ID of the issue is '96819'
I assume this will soon be fixed now.

My PleskX.pm got patched.
It will probably soon be fixed with a micro-update.

# cd /usr/local/psa/PMM/agents/PleskX
# diff PleskX.pm.orig PleskX.pm
