MongoDB Server Version Compatibility
On this page
Before you run Cluster-to-Cluster Sync, consider the following MongoDB server version limitations and requirements:
Starting in version 1.10,
mongosyncsupports migrations to destination clusters that use MongoDB 8.0. The source must be a pre-8.0 cluster. To migrate from 8.0 source clusters, see Synchronize Data Between Two 8.0 Clusters.Your source cluster must run one of the following major supported versions:
4.4 (New in version 1.10.0)
5.0 (New in version 1.10.0)
6.0
7.0
mongosyncdoesn't support MongoDB rapid releases, such as 6.1 or 6.2.
The following table lists the minimum MongoDB server version requirements for clusters:
Major Version | Patch Version | Minimum Feature Compatibility Version |
|---|---|---|
4.4 | 4.4.23 | 4.4 |
5.0 | 5.0.29 | 5.0 |
6.0 | 6.0.16 | 6.0 |
7.0 | 7.0.9 | 6.0 |
Synchronize Data Between Clusters with Different MongoDB Server Major Versions
Starting in 1.7.0, mongosync can perform version migration from
certain lower major version source clusters to certain higher major
version destination clusters.
Starting in version 1.10.0, mongosync supports migrations from pre-6.0
source clusters.
Important
mongosync does not support migrations to pre-6.0 destination clusters.
mongosync supports syncs between the following source and
destination MongoDB server versions:
6.0 Destination | 7.0 Destination | 8.0 Destination | |
|---|---|---|---|
4.4 Source | √ | ||
5.0 Source | √ | √ | |
6.0 Source | √ | √ | √ |
7.0 Source | √ | √ | |
8.0 Source |
Synchronize Data Between Two 8.0 Clusters
To migrate data between two 8.0 clusters:
Use mongodump to export data from the source cluster.
Use mongorestore to import the data into the destination cluster.
For limitations on using mongodump and mongorestore, see
mongorestore Behavior, Access, and Usage.
Alternatively, you can downgrade your 8.0 source cluster to 7.0 and then migrate your data into an 8.0 destination cluster.
