Version Upgrade : 1.9-pr5 to 1.9-pr8

Hi All, i would like to ask for a helping hand, i'd been making a lot of virtual tour, i found i need to update the version to fix some bugs, all the virtual tour is made using krpano tool 1.9-pr5, is there a proper way to update the version without recreating everything?

thanks in advance.

Run krpano Tools.exe, there will be a built-in utility for updating
