EPiServer CMS bug when upgrading with deployment center

Error described:

At C:\Program Files (x86)\EPiServer\CMS\6.0.530.0\Upgrade\System Scripts\Upgrade Site (SqlServer).ps1:361 char:29

+                  $newUiUrl = $uiUrl.Replace <<<< ($uiPath, $uiPath+"/CMS")

System.Management.Automation.ParentContainsErrorRecordException: Cannot convert argument "1", with value: "/CMS", for "Replace" to type "System.Char": "Cannot convert value "/CMS" to type "System.Char". Error: "Strängen måste vara exakt ett tecken lång."" 

The problem is that the site had asolute url for ui in sitesettigns, because of ui running under SSL.

Changing the value to ~ui solved the problem.

Conclusion, you can not upgrade sites using https with their tool, without manually fixing this
