README

Adds a migration command to migrate content blocks from the Content Blocks Registration API to TYPO3 CMS Content Blocks.

What does it do?

copy old content blocks to new place (folder ContentBlocks/ContentElements/)
build new folder structure
- delete unnecessary files (e.g. composer.json)
- rename files (e.g. language files, icon file)
- rename folders (e.g. src to Source and dist to Assets)
- adjust language files
convert the EditorInterface.yaml
adjust template files (only Frontend.html and EditorPreview.html)
- (adds the "data-" prefix to all variables which are not declared as "useExistingFields" in the EditorInterface.yaml)
- convert the EXT:content_blocks specific ViewHelpers
convert database structure

What does it not do?

Considers Collections on first level (Collections in Collections ... in Collections ... are not tested/supported)
Template adjustments must be done manually (the migration only adjust the above-mentioned parts)

Important notes / before you start

Be sure to have a backup of your database and files (if not, do it before you start)! This migration should not be executed on a live system without a backup! An additional question will be asked before the migration starts, so you have the possibility to cancel the migration before things get changed.

Command details

ddev typo3 content-blocks:migrate --target-extension=EXTENSION --vendor-name=VENDOR_NAME --package-path=PACKAGE_PATH --source-content-block=CONTENT_BLOCK_PACKAGE

--target-extension (required): The extension key of the target extension where the content blocks should be migrated to.
--vendor-name (required): The vendor name of the migrated content blocks.
--package-path (required): The path to the package of the "old" content blocks which should be migrated (relative from document root).
--source-content-block (optional): The package key of one "old" content block which should be migrated.

Drawbacks to keep in mind

If you migrate the database structure, it is possible that you get a "Row size too large" error while running database updateschema.

Sometimes it is enough if you run the database updateschema command again with additional argument like "table.add". If this does not help, you have to analyze the database structure manually based on the information from the "Row size too large" error and execute some necessary SQL queries.

Troubleshooting and logging

If something does not work as expected take a look at the log file first. Every problem is logged to the TYPO3 log (normally found in var/log/typo3_*.log)
