Hi, I am trying to upgrade a local instance of ES from version 0.2 to 2.1.1. Yes I know this is a pretty big jump. This is what happens when you stay out of the loop for a couple of years. As far as I understand, the process is pretty simple. This is what I've done: - Make a back up of my data directory - Install and run ES 1.7.4 - Upgrade each index individually by running POST to indexname/\_upgrade - Verify nothing else needs to be upgraded by running GET to \_upgrade (each index displays number of bytes that need upgrading as 0) - Install and run ES 2.1.1 - I receive the following error: `The index [policies] was created before v0.90.0 and wasn't upgraded. This index should be open using a version before 2.0.0 and upgraded using the upgrade API` Note that I used the following documentation to upgrade my indices: [https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-upgrade.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-upgrade.html) Any ideas why the upgrade process failed? How can I check which version each of my indicies is at? ---

I guess that `policies` is one of the indices you manually ran `_upgrade` on, right? And nothing appeared in logs? I would probably open an issue about this. ---

Yes policies is one of the indices I upgraded. I have 11 indices in total. I upgraded them all individually. When I start 2.1.1 I get that error above for just two indices (enquiries and policies) and the error appears twice for both for some reason. ---

I think you should open an issue then... ---

0.2? Wow. Perhaps you meant 0.20? 0.2 would have been very very early. 🙂 After upgrading to 1.x, try doing a forced merge down to one segment. Perhaps some segments are still old. Since Lucene segments are immutable, a forced merge will create a new Lucene 4 segment out of the old segments. Ivan ---

Yes, I meant 0.20, not 0.2. It seems unfortunately that 1.7 does not support the forced merge operation. ---
