Hi Denis,

yes, this is about PDS + entry expiration (TTL).

Please note there is second issue, than is visible by user
https://issues.apache.org/jira/browse/IGNITE-6964

'transfer of old entries to new storage' means DB entries migration from
old format to new. We defenetely should have PDS compatiblity test for this
case.

Sincerely,
Dmitriy Pavlov
