Hi Expert,

Currently we have PMM1.17,1 installed using docker on our test environment . so now we are planning to update PMM2.2 , so while updating i am facing below issues

1 \> chown: invalid user: ‘mysql:mysql’ while restoring pmm-data backup  
2 \> after updating pmm2 its still showing 1.17.1 version on pmm GUI tool

I tried below steps to update pmm2.2

docker stop pmm-server

docker cp pmm-data:/opt/prometheus/data opt/prometheus/  
docker cp pmm-data:/opt/consul-data opt/  
docker cp pmm-data:/var/lib/mysql /root/pmm-data-backup/var/lib/  
docker cp pmm-data:/var/lib/grafana /root/pmm-data-backup/var/lib/

docker rename pmm-server pmm-server-backup  
docker rename pmm-data pmm-data-backup

docker create -v /opt/prometheus/data -v /opt/consul-data -v /var/lib/mysql -v /var/lib/grafana --name pmm-data percona/pmm-server:2.2 /bin/true

docker cp /opt/prometheus/data pmm-data:/opt/prometheus/  
docker cp /opt/consul-data pmm-data:/opt/  
docker cp /root/pmm-data-backup/var/lib/mysql pmm-data:/var/lib/  
docker cp /root/pmm-data-backup/var/lib/grafana pmm-data:/var/lib/

docker run --rm --volumes-from pmm-data -it percona/pmm-server:2.2 chown -R pmm:pmm /opt/prometheus/data /opt/consul-data  
docker run --rm --volumes-from pmm-data -it percona/pmm-server:2.2 chown -R grafana:grafana /var/lib/grafana

docker run --rm --volumes-from pmm-data -it percona/pmm-server:2.2 chown -R mysql:mysql /var/lib/mysql

Here only i am getting error chown: invalid user: ‘mysql:mysql’)

docker run -d -p 80:80 -p 443:443 --volumes-from pmm-data --name pmm-server --restart always percona/pmm-server:2.2

Please help me out to resolve this issue.

Thanks  
Gajendra

Unfortunately there Is now way to update from pmm1 to pmm2 with save data.  
In pmm2 there is a different data storage model. So there are no way to migrate. You need to setup new pmm-server and use it from scratch.
