["Chetan Mehrotra (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/OAK-6271?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16089338#comment-16089338 ] 

Chetan Mehrotra commented on OAK-6271:
--------------------------------------

Import support is now complete. Following aspects are supported

h3. Importing via oak-run

If the indexing is done in read only mode then the generated indexes can be imported via oak-run using following command

{noformat}
java -jar oak-run*.jar index --index-import --read-write --index-import-dir=<index dir> /path/to/segmentstore
{noformat}

Here "index dir" is the directory containing index files as generated by oak-run index command

h3. Importing via MBean

The indexes can also be imported via {{IndexerMBean#importIndex}} operation

h3. Points to note

* Currently the MBean is only present in trunk
* The oak-run import should only be used against an Oak setup with matching version i.e. Oak version application and oak-run should be same in terms on major and minor version. So currently it can only be used for application using Oak 1.7.x
* For older version plan is to implement a groovy script which can then be used to import it on that setup
