Layouts That Won't Migrate
Because of the changes in the layout systems used in the old and new versions of Web Express, layouts that have blocks placed in some regions will not be able to properly migrate. The content blocks, such as text blocks, hero blocks, and calendar blocks will all be migrated but the page will need to be reassembled after the site has been migrated.
Hybrid Columns
While sections with columns can be migrated to the new version of Web Express, the new layout sections cannot contain blocks that span columns.
In this example, There is a text block followed by a block row that contains two columns.
In the migration process this would be split into two unique sections, but might have some display issues that would need to be addressed.
This is a nested text block.
This is a nested text block.
Some Block Titles Won't Migrate
Because the new layout sections and layout columns are no longer blocks, they won't have titles.
If you've used the title fields on layout blocks (Block Sections and Block Rows for example), the titles will not appear after a site has been migrated.
