The Customization stage shows the destination structure as a tree on the left and the options for the selected node on the right. By default every table, field, and index is ticked - uncheck the items you do not want to migrate.
Three levels of options
Click a node in the tree to open its options panel:
- Database - settings that apply to the whole migration (overwrite, parallel threads, quantization, sync logs, garbage symbols, global type mapping, naming conventions).
- Tables - defaults that apply to every table (copy structure, copy indexes, copy foreign keys, sync types for DBSync).
- Table / Field / Indexes / Foreign Keys - per-object overrides.
Reference pages:
- Database and table options
- Field, index, and foreign-key options
- Conditional migration and data filters
Errors and warnings
Issues that would block conversion are highlighted in the tree - red for errors, yellow for warnings. Each marker links to an explanation under the tree.
See Pre-migration checks for the catalog of messages and how to resolve each.
