Description

Due to bug in https://issues.apache.org/jira/browse/IGNITE-10348, after storage migration from 2.7- to 2.8 any updates of metastorage are not persisted.

S2R:
(on 2.7)

• Activate persistent cluster with 2 nodes
• Shutdown the cluster

(on 2.8)

• Start cluster with 2 nodes based on persistent storage from 2.7
• Start 3rd node
• Change baseline
• Shutdown the cluster
• Start initial two nodes
• Start 3rd node (join is rejected: first two nodes has old BLT of two nodes, 3rd node has new BLT of three nodes)

Reproducer is attached.
