Hello.
I’m currently using PMM1.
I want to upgrade PMM1 to PMM2 with preserving data.
How do I upgrade from PMM1 to PMM2?
Thank you.
Hi @youngjae7732
PMM 2 is designed to be used as a new installation — please don’t try to upgrade your existing PMM 1 environment.
You need to re-install and configure PMM.

Hello
I think that it isnt possible:

To use PMM2 you will need to remove any earlier versions of PMM Server and Client as there is no in-place upgrade path for historical data, and then download and run our latest software.
Hi,
Also here is the instruction of how-to use both clients on the same host.
