NotePrior to 2.0, YSQL was still in beta. As a result, 2.0 release includes a backward incompatible file format change for YSQL. 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+. Export from old cluster and import into a new 2.0+ cluster is needed for using existing data.
