about the compaction strategy upgrade

I have a cassandra cluster with 2T data at each server. I used SizeTieredCompactionStrategy, and I want to upgrade to LevelCompactionStrategy. How can I do? I try to update the strategy to LeveledCompactionStrategy and set the sstable size to 10mb, then all the files are in L0, this will cost a lot time to finish compaction. Are there any better ideas?

Thanks.
