IWeb data migration 2024

Dear Apple community,

I have been using apple iWeb for years and I have done my whole webpage through it. I have bought a new iMac yesterday and I cannot migrate data to any similar software because iWeb doesn't exist anymore. I have EverWeb but that only allows me to copy everything manually again. Does someone know any way out of this?

I just need to copy the data from iWeb to another software and continue developing my website.
