Note on upgrades from pre 2.0 releases
Version 2.0 release includes a backward incompatible file format change for YSQL. Note: Prior to 2.0, YSQL was still in beta. This means that if you have an existing cluster running releases older than 2.0 with YSQL enabled, then you will not be able to upgrade to version 2.0 or higher release.
There are two ways to address the above note.
- If you don't care about preserving your existing data, then delete your cluster, and create a new
cluster with 2.0.x.x - If you want to continue using your existing data, then please save your data,
delete the cluster, create a new cluster with 2.0.x.x and then load the previously saved data.
