You have both options.
That both work.
Of course you will need to renew your member license first so you can obtain the newer version and the upgrade import scripts, No matter if you go with the vendor or a third party to upgrade for you.
Which costs $59.00 not $139.00 if you can prove you have a valid existing license.
Then you add the cost of someone to upgrade for you.
BTW, you don't just install the new version first.
You would copy the files over then run the upgrade script,not the install option.
