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:  
[https://www.percona.com/blog/2019/09/19/installing-percona-monitoring-and-management-pmm-2-for-the-first-time/](https://www.percona.com/blog/2019/09/19/installing-percona-monitoring-and-management-pmm-2-for-the-first-time/ "Link: https://www.percona.com/blog/2019/09/19/installing-percona-monitoring-and-management-pmm-2-for-the-first-time/")  
_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._
