How to change CMS from wordpress to Hubspot

"CMS WordPress but the speed and performance of WordPress are to much slow. So, that’s why I want to migrate from WordPress to Hubspot. "
You want to move to HubSpot… For speed and performance…? Lol. Thats a poor choice.
If your WordPress site is slow it’s probably because you’re using some horrendous page builder, a thousand plugins, and other poor practices. Clean it up.
At least on WordPress you have the control and can fix those things. On HubSpot… You’re extremely limited in what you can do and stuck with horrendous product decisions due to lacking interoperability and no real programming interface outside of a contrived templating language. If you can even call it that.
Hubspot is nothing but a poor CMS and poor man’s way of doing things that tried reinventing the wheel for their “products”, is a half decade behind any competition, and instead of managing to improve anything whatsoever by reinventing the wheel they actually managed regression which is impressive.
Took the wheel and turned it into a square.

In other words, putting your technical assets in the hands of a *marketing* platform attempting to masquerade as a cms is probably not the best idea. Browse around this forum and see the level of quality you can expect for yourself.
