Vault upgrade with huge identitystore


I am experiencing great pain in upgrading the vault version from 1.1.2 to the latest 1.8.x.

Here are the problems I am facing.

  • Huge identity store, can’t even list the entities. The identityleak problem has been addressed in 1.4.x release.
  • Since vault can not be downgraded cleanly so can’t take any risks there.
  • Deletion is super slow, batch-delete is also not supported.
  • Even if I take a hit for failover time, not certain how new version of vault will deal with the identitystore which can lead to other complications.

If anyone has faced this issue, any leads would be highly appreciated.

Vault version - 1.1.2

Let me know if further details are required from my end.
