How to upgrade
Percona MySQL 8.0.23 To
Percona XtraDB Cluster 8.0.23…?
I believe the same question was already addressed here: Upgrade Percona MySQL 8.0.23-14 to Percona XtraDB Cluster 8.0
Also, this is not an “upgrade” but rather migration to another replication technology. By upgrade, we mean to use a newer software version.
Could you please let me know the steps or any other detailed documemation to migrate from
Percona MySQL 8.0.23 To Percona XtraDB Cluster 8.0.23.
My use case is - iam having a 4 node replication setup , how would i migrate …?
The general idea is similar as described in this bit old webinar: Migrating To Percona XtraDB Cluster
The best option IMHO is to configure one of the current replicas as a PXC node, bootstrap it, while letting it continue async replication. Later, other replica nodes can be migrated too, but async replication should be enabled on just the first migrated one.
For configuring PXC, follow the documentation: Configuring Nodes for Write-Set Replication
