Roman Puchkovskiy updated IGNITE-26107:
---------------------------------------
    Description: 
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 node is stopped, its binary is replaced with v2, the node is started.

After that:
 # The values that were inserted should be read back
 # The values that overwrite earlier values should be read back
 # The values that were removed should NOT be read (null should be returned)

  was:
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 storage is flushed and the node is stopped, its binary is replaced with v2, the node is started.

The tests have to ensure that aipersist-based tables work correctly:
 # all data written in v1 can be read in v2
 # including overwritten versions
 # deleted data cannot be read
 # updates that are rolled back cannot be read

Here are variations that need to be tested:
 # When there were no unmerged delta files in v1 (that is, after the writes are finished on v1, we wait for all delta files to be merged and removed)
 # When there were some unmerged delta-files
 # When unmerged delta-files remain from v1 and we start creating new delta files immediately after starting on v2, and THEN we start verifications listed above (while the delta files are still there)
