Lark Docs migration error code descriptions and solutions

4 min read
I. Intro
After you complete the migration of Lark documents, wiki spaces, and/or documents from third-party software, you can open the Lark Admin Console and navigate to Settings > Data Migration. Here, you can click the corresponding migration section and find the migration report in the migration record details. This report will display a list of files that were successfully migrated or failed to migrate.
If you are migrating documents from one Lark account to another, the migration tool's bot will send you a migration report. For specific information, please contact the person in charge of setting up the migration tool at your organization.
