Good stuff! Given it supports setups way back to 1.0
bq. It seems 1.0.* don't have CheckpointManager mbean. I worked around it by
creating one by NodeStore api. Do we want to do something about it?
Yes 1.0 did not had that. For now lets claim support till 1.2.
* For 1.6 we need to set "uid" property (timestamp) in ":status" node (see
usage in LuceneIndexEditorContext#configureUniqueId) otherwise copy-on-read
logic would fallback to old mode (using reindex count) for copying files. So
just set such a property prior to commit. This can be done irrespective of Oak
version. For older setup it would not be reead

> Key: OAK-6453
> URL: https://issues.apache.org/jira/browse/OAK-6453
> Project: Jackrabbit Oak
> Issue Type: Improvement
> Components: indexing, run
> Reporter: Chetan Mehrotra
> Assignee: Vikas Saurabh
> Labels: docs-impacting
> Fix For: 1.8
>
> Attachments: IndexImportScript.groovy
>
>
> The indexing tooling implemented in OAK-6081 can be used to perform reindex
> and import the indexes for any Oak 1.7+ setups. For older setups we would be
> using 2 phase approach
> # Perform [out-of-band
> indexing|https://jackrabbit.apache.org/oak/docs/query/oak-run-indexing.html#out-of-band-indexing].
> This can be done via oak-run from 1.7.x against any older version of Oak
> # Import index - For this step we cannot use oak-run from trunk for older
> branches as write operations would not be compatible with older version of
> Oak.
> For import then we have 2 options either
> # backport all the work in OAK-6271 to older branch
> # OR implement a script which can be used with oak-run or Felix Script
> Console to just import the lucene index with any other manual step
> Purpose of this task is to implement such a script
