Cannot mount the projects from Docker Image JBPM 7.10.0 Final to JBPM 7.30.0 Final Image

Hello Team,

We are upgrading our JBPM Server from 7.10.0 to 7.30.0 version. We have prepared the docker image to do the needful. We have to migrate the projects and business processes from 7.10 to 7.30.

In our New Docker compose file (for 7.30 version) we have created a seprate git repo volume and copied the contents from git repo volume of 7.10 versioned image. We found the .niogit directory of new image has projects from old image and we restart the container.

We are suppose to see the projects in console along with spaces but we are not able to see those.
Please suggest some guidelines or steps to overcome this challenge.

Thanks
