Unable to create or update WebPart

Symptoms

When attempting to migrate a Web Part, Sharegate displays the following message : 

• Unable to create or update WebPart. In Office 365, this is mainly caused by the farm setting "Custom Script" being deactivated.

Error code

• WP-027-076

Details

There is a setting called  Custom Script in Office 365 which allows the administrator to choose whether custom scripts are enabled or disabled on a site. 

Since web parts function as custom scripts, Sharegate will not be able to migrate web parts if custom scripts are disabled. 

Note: Custom scripting capabilities are disabled by default for:

• Personal sites
• Self-service created sites
• The Root Site Collection of the Tenant

Solution

You must enable custom scripts in your settings and retry the migration. 

To enable custom scripts:

Sign in to Office 365 

Click the app launcher icon

Click  Admin

Select  Settings

Under  Custom Script select:

• Allow users to run custom script on personal sites.
• Allow users to run custom script on self-service created sites

Click  OK 

It takes 24 hours for changes to this setting to take effect.

Note: This solution does not apply when migrating to Modern Team Sites in Office 365 at this time.
