About new purchase for Parallels Desktop Pro Edition

Hi there, I have been purchasing "Parallels Desktop for Mac Subscription" for a few years already. Here is my previous subscription:

```
Status Expired
Activation Date 06/07/2022
Next Billing Date 08/07/2025
Renewal Price NZD 248.57
```

Of course, it's already expired (as I switched to a Linux/BSD laptop for a while). But I need to use MacOS again for my new job, and I do want to continue using Linux/BSD inside Parallels Desktop, so here is my question:

My original subscription price is too high. I saw the email you guys sent to me, then I saw this after clicking the link from the email:

```
Parallels Desktop
Pro Edition
For: Developers, creators, and power users
Save 35%
$77.99/year$119.99 (around NZD 133)
Subscription
```

That's for the `New` tab. If I click `Upgrade`, then I see this:

```
For all one-time purchases and customers with a previous version of Parallels Desktop,
upgrade to the latest version at a discounted rate.

Parallels Desktop
Pro Edition Upgrade
Free upgrades to newer versions.

Save 62%
$45.49/year$119.99 (around NZD 77)
Subscription
```

Could I go through the `Upgrade` option? If yes, what extra steps do I need to take to apply the upgrade purchase to my account? (e.g. Do I need to delete the old subscription and add the new one?)

Thanks for the help
