change-stack not working from cflinuxfs2 to cflinuxfs3
if i have a app with cflinuxfs2 on buildpack(java-buildpack v3.9-offline) name which is not available in cflinuxfs3

it says a problem occurred: no app found with the name

Any possible solution for this issue without using cf push as i want to use the alredy deployed source code and change the stack from cflinuxfs2 to cflinuxfs3
