The Wiki Page Library and Enterprise Wiki do not use the same content types and they do not use the same property to hold the page's content.
Because of this, there are 2 mappings that must be done in order to correctly copy wiki pages from a wiki library to an Enterprise Wiki with Sharegate.
- The first mapping that must be done is with Map Content Types to map the content type "Wiki Page" to "Enterprise Wiki Page".
- The second mapping that must be done is with Map Properties to map "Wiki Content" with "Page Content".
Furthermore, an additional step is required to set the appropriate Page Layout.
- Copy the pages using a Custom Property Template: in the Metadata section, for the Enterprise Wiki Page content type, set the Page Layout to Set custom value and choose the appropriate page layout (ex.: (Enterprise wiki Page) Basic Page).
