You can upgrade directly to last 8.6 from your 6.1.4.
You'll upgrade Pub, install new license, then upgrade Subs. Of course better to do backup before, although upgrade goes to second partition and you always can revert server to old version by switching between active-inactive software partitions.
Send me private to communicate on russian.
