Migrating from 5.5 to 5.7

Hello all

I have server on percona 5.5, and want to upgrade to 5.7 without downtime

Can i create replica-server on 5.7, migrate data (about 150gb) to it with xtrabackup, and have configuration with master 5.5 -> slave 5.7, then change slave and master and upgrade master server to 5.7?
