Hi,
I would like to Migrate all the PMM server docker data to new server without any data loss. We are actually Migrating our servers from Centos to Rocky Linux so, we want to migrate PMM Server(Centos) to Rocky Linux new server.

Well, as fate would have it, we’re actually just about to release our PMM Server on a EL9 based image, Oracle Linux 9 specifically.
In order to guide you on the migration we’d need to know a bit about how you’ve installed PMM. Can you provide the following:
du -sh /srv/
should give enough info for that.pmm-admin config
command you run on the clients can help answer this).There may be more info needed but this helps provide the best outline of the steps you’d need to take. The process is pretty straight forward and I’ve been doing it myself for several months now including live customer migrations.
Here are the details:
du -sh /srv/
should give enough info for that. – 43GB
pmm-admin config
command you run on the clients can help answer this). – IP
Please let me know if you need more details on the same.
Ok, it’s pretty straight forward then. I assume you’re going to want to create a parallel system to the existing one so you can have time to install/configure/tune your host OS, get PMM up and running, migrate your data, then perform the final cutover. You can do it all in place too but you’ll lose metrics.
There’s a EL9 based 2.36.0 docker already available you can pull it from perconalab/pmm-server:2.36.0-el9
this has gone through all the same testing and validation that the EL7 container gets and has passed QA.
The steps are:
docker run
you did on the old system only substitute the el9 image over the default el7 one.That’s basically it! Read the steps over and ask any questions…it will help us solidify the instructions we publish!
@steve.hoffman I appreciate your providing such thorough instructions. I’ll try the aforementioned process and report back to you on the results.
