Nick Bailey commented on CASSANDRA-5524:
----------------------------------------
so, scrub currently already has the side effect of upgrading sstables and is
already offline.
what if we modified scrub to be able to work on snapshots as well as live
sstables?
> Allow upgradesstables to be run against a specified directory

> Key: CASSANDRA-5524
> URL: https://issues.apache.org/jira/browse/CASSANDRA-5524
> Project: Cassandra
> Issue Type: Improvement
> Components: Tools
> Reporter: Tyler Hobbs
> Assignee: Nick Bailey
> Priority: Minor
>
> Currently, upgradesstables only modifies live SSTables. Because
> sstableloader cannot stream old SSTable formats, this makes it difficult to
> restore data from a snapshot taken in a previous major version of Cassandra.
> Allowing the user to specify a directory for upgradesstables would resolve
> this, but it may also be nice to upgrade SSTables in snapshot directories
> automatically or with a separate flag.
