Migration of 1C Enterprise from version 8.2 to 8.3 SQL

Question

1C

At the moment there are 3 configurations: BP (Enterprise Accounting), ZUP (Salary and Human Resources), self-written on the platform 8.2
New BP updates ask for 8.3, if everything is simple with the file version, then how to switch to 8.3 sql, partially? So that the self-written one works on 8.2, and the PSU and ZUP on 8.3.
How to make 2 servers 1c work?

Answer 1

Install server 8.3.
In the installation wizard, specify "Install 1C:Enterprise server as a Windows service (recommended)".
The server will install, but due to a port conflict with the 8.2 server, it will not start.
Next, go to the registry
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ We are
looking for the branch
1C:Enterprise 8.3 Server Agent
or
1C:Enterprise 8.3 Server Agent (x86-64)
In this branch, edit ImagePath - change ports
For example, it was
"C:\Program Files (x86)\1cv8\8.3.4.389\bin\ragent.exe" -srvc -agent -regport 1541 -port 1540 -range 1560:1591 -d "C:\Program Files (x86)\1cv8\srvinfo"
became
"C:\Program Files (x86)\1cv8\8.3.4.389\bin\ragent.exe" -srvc -agent -regport 2541 -port 2540 -range 2560:2591 -d "C:\Program Files (x86)\1cv8 \srvinfo" The
server can then be started from the Services console.
When adding new 1C databases as a cluster, specify ServerName: 2541

Answer 2

Why, self-written can not be translated into 8.3? In the configurator, you can set the compatibility mode with 8.2. Two servers are installed on different ports.
