Prior to version 0.9.0 it required the source and target to run the same major version, which ruled out the lift-and-shift move most migrations want: going from an older major like 6.0 straight onto a newer one like 8.0.

A Percona PostgreSQL operator pgBackRest restore is the simplest way to move off the Crunchy Data PostgreSQL Operator: take a full Crunchy backup, point the new Percona cluster’s dataSource at the existing pgBackRest archive, and the cluster bootstraps from it before its first start. This post covers that path, plus a second option, persistent-volume reuse, for...
tidesdb-mysql is an experimental build that was developed to verify how TidesDB, the LSM-tree key/value engine, can work with MySQL 9.7 as a storage engine.
