$ php app/console ezplatform:io:migrate-files --from=default,default --to=dfs,nfs --env=prod
The command ezplatform:io:migrate-files migrates files from one IO repository
to another. It can for example be used to migrate local files from the default
IO configuration to a new IO configuration, like a clustered setup.

NB: This command is experimental. Use with caution!

The --from and --to values must be specified as <metadata_handler>,<binarydata_handler>.
If --from is omitted, the default IO configuration will be used.
If --to is omitted, the first non-default IO configuration will be used.

During the script execution the files should not be modified. To avoid
surprises you are advised to create a backup and/or execute a dry run before
proceeding with actual update.

Since this script can potentially run for a very long time, to avoid memory
exhaustion run it in production environment using --env=prod switch.
