Scripts for mapping content migration

Often, you need to update your documents in bulk – for example if you decide to change a translation of a common term or replace a widely-used asset with a different one.

With the help of a bulk update script, automating these updates via the Migration API saves time and ensures you cover all affected documents. We cover the following examples:

• Retrieving all existing documents from the Document API
• Or fetching documents in batches if you have a repo with a lot of content
• Inserting a new field with new content in each document
• Making a PUT request to the Migration API using the updated document content

On the basis of an example of migrating HTML content of a 2 language website into a new Prismic repo, the Migration API scripts demonstrate the following steps:

• Extracting and uploading of media to the Asset API, either via URL or via files
• Inserting media ids into your document content
• POSTing documents
• Creating localized translations of original language documents
• Updating content to resolve links between documents
