Most likely, since the underlying mechanism hasn't changed much. It's the same process as the disk format conversion, and there are multiple different ways to accomplish it, but they all involve getting one drive empty, formatting it, copying data from the next drive to be formatted, etc.
BTW, if you are planning to run encryption, make sure your backup strategy is complete and as foolproof as you can get it, because if you have an issue, recovering data from encrypted volumes is orders of magnitude harder, so it's best to just restore from backup if you have an issue. Parity is NOT a backup, it's realtime, so if something corrupts your data, or a drive fails and one of the other drives has an issue while rebuilding the failed drive, you are sunk without backups.
