After changing host name, I got some issue to access QMC and Hub address of Qliksense, then I uninstall and re-install Qliksense server after backup C:\ProgramData\Qlik\Sense\Apps folder. How can I restore all apps in that folder to new server Qliksense? Files in this folders is not *.qvf, then I cannot import them via QMC, I tried to copy them to new C:\ProgramData\Qlik\Sense\Apps folder, but it didn't work.
I found the solution: just rename and add extension (.qvf) to the files and import via QMC
