How to import a catalog from TP in birix?

Question

1C-Bitrix

Hello.
There is a catalog with trade offers that needs to be transferred to another server.
I tried to upload xml csv, everything is uploaded correctly, but trade offers are not associated with products.
Product type: simple
TP: offer without product
How to transfer the catalog correctly so as not to lose dependencies?

Answer 1

TPs are not associated with products, because the ID of the products themselves has changed, so there are no bindings.
Go through the script and match the identifiers (as far as I remember, the external code after import stores the id of the original element, but this is not accurate). If the guides are stored there (exchanged with 1C), then it's even better to compare them with them

In general, it's more reliable to transfer the SQL dump if the other server is "naked"
