Step by step MariaDB move from one server to another

I need to move my DB from old server to new one. Downtime is not much sensitive for me.

So I made a backup on old server:

xtrabackup --backup --datadir=/var/lib/mysql/ --target-dir=/data/backups/base/

Next I prepare it:

xtrabackup --prepare --apply-log-only --target-dir=/data/backups/base

Next I copied backup to new one:

rsync -zavP user@ /backup/some/dir/on/new/server

… some time passed … (7-8 hours) database is pretty big one Now I need incremental backup for this 7-8 hours I do incremental backup on old server:

xtrabackup --prepare --apply-log-only --target-dir=/data/backups/base --incremental-dir=/data/backups/inc1

What should I do next? My assumption is: 1. Copy incremental backup, and apply it in base and do

xtrabackup --copy-back --target-dir=/backup/some/dir/on/new/server

OR 2. Apply base backup without incremental and THEN apply incremental backup?
