Everything I've read over the past few weeks regarding upgrading Opencart from very old version to current, seems fraught with danger
I have offered to help freshen up someone's existing store. Have not had access to it yet so I only know that it was created a few years back so likely a very old version.

What is the risk of leaving her with the old version of Opencart and simply customizing a new theme?

Her existing site: www.sueshappytails.com
I'd used Opencart 3 to test a new theme but it comes in older versions www.billieraven.com/happytails

- Not being kept up-to-date with service providers changes
- Not updated with CSS / Bootstrap changes
- Not updated with jQuery adaptation code changes
- Not updated with the OC events structure
- Don't have additional features built-in from both ends - admin and store-front end

The rest goes to extension compatibility and custom codes.

The most generated errors being found on Opencart forum originates from contributed programming. The increased post counters are caused by redundancies of the same solutions that were already provided prior.

Well, it might depend of the exact OC Version used, but generally, neither
Bootstrap nor jQuery is a problem, since 1.5.6.x OC Versions will still work
with later Versions of Bootstrap Style and jQuery Code in full. And it only
takes one or two additional Files to change, to make it work with PHP7.2x.

Unfortunately, the Theme, shown below, is no longer available in the
OC Extension Section, but since it was released under GPL Open Source
Terms, I could spare one, if your OC Version is above OC v.1.5.5.x.

It would probably be the easiest way, to get 'responsive', in addition to
so use one of the few TOP NOTCH Performer Themes ever built.

Otherways, if you tend to move up, there would nothing be left, out
of your existing Installation, including the DB, usable again in a later
OC release, without spending a lot of time and even money, to get it
made work again.

But if your OC Version is still below v.1.5.6.x, I would at least install the
latest v.1.5.6.x Version available, just to make sure ... ;)

Merkent Theme powered v.1.5.6.5_rc Version, possibly not yet fully ready,
since I only installed it last night again, in order to build a 'basic' free
(risk-free ;) ) Version out of it:

A (hopefully still) older working and slightly modified Version 1.5.6.5 can
be seen here, equipped with that Merkent Bootstrap Theme:

Just in case ...

The security risks of running old, non supported PHP versions is a huge risk. Atleast use Qphoria's upgrade service or work with a developer for further customization and upgrades.
