Migration Error from on-premise to SharePoint Online in Office 365
Copying to an Office 365 Site Collection requires Custom Scripts to be enabled at the destination Using the Sharegate Desktop to Migrate on-premise team sites to Office 365 failed with Custom Scripts error I was able to resolve this with the following script: asnp *office* $adminUPN="Admin@orgname.onmicrosoft.com" $orgName="OrgName" $userCredential = Get-Credential -UserName $adminUPN -Message "Type the password." Connect-SPOService -Url https://$orgName-admin.sharepoint.com -Credential $userCredential $sites = Get-SPOSite -Limit all foreach ($site in $sites) { Set-SPOSite $site -DenyAddAndCustomizePages 0 } Please make sure you understand the security implications of this change. In my case, I was able to re-enable custom scripts on most of the sites following the migration without errors. Prerequisite is the SharePoint Online Management Shell
