How do I move a large existing catalogue?

Open Resources → Import multiple files. Choose Import files instead if you already have PDFs, documents or ZIPs, or paste a store link to inspect a migration path. You can also choose I have a catalogue CSV and use the downloadable template. For CSV, include title and file columns; a file can be matched by name, followed by a review of missing items. Select supported Resources in manageable batches, review the private drafts and correct anything that needs attention. Classmade saves confirmed progress to your account. Uploads, security checks and review are separate steps: nothing publishes automatically. Reopen the migration workspace to resume an interrupted session. If an item fails, inspect its error and retry that item; do not create an entirely new duplicate batch.
