Who connected the online cash register to Bitrix? Can this be done without updating?

Question

1C-Bitrix

Hi all! Got a question. Is it possible to connect an online cash register without updating Bitrix to the version when online cash registers appeared (maybe OFD or ATOL and other manufacturers have their own software that integrates with Bitrix) or will it be necessary to update?

Answer 1

You will definitely need to update.

Answer 2

Is it possible to connect online cash registers for the old Bitrix?
Yes, you can.
No.
What are the options besides upgrading?
1) With the help of developers (order) your implementation. In this case, you won’t have to update Bitrix, but all problems with the work of cash desks will only be a headache
2) You can look for available extensions for Bitrix, if the cash desk manufacturers release them. Most likely, such modules will require the presence of standard integrations, i.e. updated Bitrix, but what the hell is not joking, you can find a different implementation. (I haven't come across any yet).
As a result, you will still come to the purchase of an upgrade sooner.
