------------------------------

             Summary: Not able to move segment store directory on filesystem after closing FileStore
                 Key: OAK-5326
                 URL: https://issues.apache.org/jira/browse/OAK-5326
             Project: Jackrabbit Oak
          Issue Type: Bug
          Components: upgrade
    Affects Versions: 1.5.13
         Environment: Windows 2012 R2,
Java(TM) SE Run-time Environment (build 1.8.0_74-b02)
            Reporter: Arek Kita
             Fix For: 1.6


The JVM process that uses {{oak-upgrade}} library for upgrading Oak repository is not able to move source (and probably destination) repository after making sure that both file stores are closed.

Is there any way to make all operations synchronised and finished after the migration is executed using the API method: {{OakUpgrade.migrate(MigrationOptions options, StoreArguments stores, DatastoreArguments datastores) throws IOException, CliArgumentException}} 

This leads to a weird experience when filesystem clean up (reordering) is needed.

On Unix the {{segmentstore}} folder might be moved as UNIX fs implementation is not so restrictive. On Windows it is not possible.
