I've manually duplicated our 2nd website because of problems we were having (as can be seen here: 'Unique constraint violation found' - when updating existing orders )

I have done the following:

• set up a new website, store and store front
• connected the new website to the existing categories (from the old 2nd website)
• I've gone through the products and added them to the new website
• I've added the new website/store/storefront to the appropriate CMS pages and blocks
• I've added extension configuration to include the new website

Then I've done a test order and:

• The great news is - I don't have the same problem with updating orders which I had on the old website (as referenced above)

• there are, however, 2 problems:

  1. The websites do not share the same customer information (login info etc.)

  2. I get the following Error after submitting an Order:

  Invalid Form Key. Please refresh the page.

(the order is submitted but the Error comes up which will annoy customers)

How to resolve #1 and #2 above?

UPDATED on November 23rd, 2021:

What I want to do is the following:

I have these websites in the same Magento install:

• website 0
• website 1
• website 2
• website 3
• website 4
• website 5

I want to share customer information only between store 2 and 5. Would I be able to use this Export/re-import process?

-> System -> Data Transfer -> Export -> select website 2 in the 'Associated to Website' drop-down here:

Then Import this into website 5? Would this work?

I have tried the Customer Export and re-import as stated above but it does not appear to be working. Would anyone know why that might be? I have documented that in more detail here:
