Ivan Rakov created IGNITE-12531:
-----------------------------------

             Summary: Cluster is unable to change BLT on 2.8 if storage was initially created on 2.7 or less
                 Key: IGNITE-12531
                 URL: https://issues.apache.org/jira/browse/IGNITE-12531
             Project: Ignite
          Issue Type: Bug
    Affects Versions: 2.8
            Reporter: Ivan Rakov
             Fix For: 2.8


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)
