How to transfer part of orders from Bitrix to Bitrix?

Question

1C-Bitrix

I finalized the site on a copy, during this time new orders for IM were accumulated on the main site.
How can they be transferred to a copy, supplementing it with new orders?
Pull the file from the muscle option?
Similarly, I would like to transfer coupons.

Answer 1

In 2019, it is impossible to transfer new orders in an online store with a connected cash register.
In practice, you will have to take into account too many subtleties, but in the end you will still come to the conclusion that transferring your developments (infoblocks, code, cart rules, etc.) will be an order of magnitude faster than transferring information from one site to another.
As for the transfer: it is strictly forbidden to transfer individual records from the table - either the entire table, or nothing. Especially if you do not know the architecture of 1C-Bitrix

Answer 2

If you did not update Bitrix (some updates may change the structure of the database), then restore the database separately and the whole business.
Otherwise, you need to write a module or a separate script that creates missing users, orders, payments, and shipments. Plus, there is still a slight tuning of individual fields through direct access to the database, otherwise, for example, everything will be re-uploaded to 1C. If business processes are configured for some stages, then they will also need to be pulled / muffled.
In general, work is about 20 hours, if you have already done it, if not, then dig for 2 weeks.
