Not every property that is stored in Elastic Core persistence can be migrated one-to-one to the SQL persistence.

Due to technical reasons string properties have a length limit in the SQL persistence. When a string is too long it will be truncated and an issue is created in the report. If you want to change the truncated value you can either adjust it after the migration in the migrated Project, or you adjust the property in the Elastic source and re-execute the migration.

Custom Project properties are not migrated and their existence will be reported. To resolve this you should convert these properties to additionalProperties.

To-dos that have a target which is not a Project cannot be migrated and will create an issue.

For more details on the restrictions for the SQL persistence see Section, “API”.
