16## Known Issues
17
18-> **NOTE:** This is a known issue applicable to _Vault Enterprise_.
19
20During upgrades to 1.1.0, 1.1.1 or 1.1.2, Vault replication secondaries may
21require an automatically-triggered reindex, either if upgrading from a pre-0.8
22version of Vault or if a previously-issued reindex operation has failed in the
23past. In these reindex scenarios, the secondary cluster will perform a complete
24WAL replay, which can take a long time and is a partially blocking operation.
25
26This is fixed in [Vault
271.1.3](https://github.com/hashicorp/vault/blob/master/CHANGELOG.md#113-june-5th-2019),
28and we recommend upgrading to Vault 1.1.3+ rather than any prior 1.1.x version.
29We also strongly recommend upgrading your Vault cluster to 1.1.3 if you are
30running Vault Enterprise 1.1.0, 1.1.1 or 1.1.2.
