Help from our friends:XMLstarlet + BBEdit

CODE!(and migrate_ui)

Special challenges

• You know, other than the lack of documentation and size of the exported data

• base64 encoding, sometimes• $row-­‐>xml-­‐>{'body'}['encoding']  - print_r() doesn’t always help

• Joins. O, Joins!• Tried MigrateSourceMultiList, ended up caching or doing lookups

• Sometimes manually loaded migration maps

• Can’t rollback followups

• Drupal doesn’t use UTF8mb4 — can’t store emoji

drush

• Migrate help:drush  help  -­‐-­‐filter=migrate

• Migrate status:drush  ms

• Import, with cunning use of flags:drush  mi  MigrationName  -­‐-­‐limit=“900  items”  -­‐-­‐feedback=“100  items”  -­‐-­‐instrument

• Force a dependent migration to run:drush  mi  SubMigrationName  -­‐-­‐force

• Roll back:drush  mr  MigrationName

• Stop a runaway/slow migration (don’t Control-C!):drush  mst  MigrationName
