How Do I Evaluate the Compatibility When Migrating MongoDB from a Later Version to an Earlier Version?

DDS of a later version is compatible with that of an earlier version. In a few cases, if a function is terminated, official information will be summarized and released. When DDS of a later version is migrated to an earlier version, new functions of the later version will not be supported in the earlier version. You need to evaluate whether these new functions are needed in your businesses.

The evaluation methods include estimation suggestions and drill suggestions.
  • Estimation suggestions: By querying the version release of the community document, you can view the new features when a new version is released and analyze the features one by one to determine whether they are used in the service code.
  • Drill suggestions: Use Data Replication Service (DRS) or mongodump and mongorestore provided by the community to migrate data to an earlier version, test the function simulation, and check whether the migration is feasible.

If your businesses are complex, contact Huawei technical experts for professional evaluation support.
