> Key: IGNITE-26106
> URL: https://issues.apache.org/jira/browse/IGNITE-26106
> Project: Ignite
> Issue Type: Improvement
> Reporter: Roman Puchkovskiy
> Priority: Major
> Labels: ignite-3
>
> Legend: v1 is original version (3.0), v2 is current version (version from
> main branch).
> It is supposed that data is written in v1, then the Metastore storage is
> flushed and the node is stopped, its binary is replaced with v2, the node is
> started.
> We must test the following scenarios:
> # MG repair after upgrade
> ## Metastore is created (and flushed) on v1 for a cluster of 3 nodes (ABC);
> MG leader is node A
> ## v2 nodes are started on the same work dirs (only for nodes BC; a is not
> started)
> ## MG repair is performed to make B or C a leader
> # Upgrade after MG repair (perform the same repair steps as above and then
> do the upgrade)
