Is it difficult to upgrade the site and admin panel on opencart from 1.5 to 2+?

Question

CMS

Friends.
I am a full-cycle developer and I hardly understand the intricacies of programming. Basically, I had to work with wordpress or make self-written sites. But then an order came from opencart. You have to start somewhere. Found a specialist, unfortunately, not on the recommendation. He told me that the transfer of the site (about 2-3 different pages in the template) to an updated version of opencart and, accordingly, the admin panel (there is a small part of individual adjustments there, but again I cannot know this) will take 1.5-2 weeks and will cost 18,000 rubles. OK. In terms of time, it is obvious that he has parallel projects and everything can be done much faster, I feel it. But in general, can you tell me from your expert side, comment on this situation? I already fucked up the deadline (people do everything and do something, I guess pulling time) and as a baby in a supermarket I don’t know the nuances. Haple is short.

Answer 1

Well, what can I tell you, you were simply divorced due to lack of experience and understanding of the process. In fact, this can be done both faster and cheaper and not 2-3 pages.
