The Large List Selector control has been updated with a new pagination control, the smooth panel update feature and interactive search.
During migration, existing Large List Selector files are replaced with new Large List Selector files. Customizations you have made to the Large List Selector files will not be retained.
After migration, re-apply any customizations you may have made to the original Large List Selector files to the new Large List Selector files.
