We have been running an algorand indexer v2 with our algo node, following tis document: Install the indexer - Algorand Developer Portal
However even though the node is syncing ahead, the indexer sync has been stopped at 30077385
I see there is a v3 release. How do we migrate from indexer v2 to v3?
I also see a dockerimage available to indexer now: algorand/indexer
What should be our docker run command to use this image in case we want to start indexer from start?
