How to switch ENOVIA to connect from CATIA V5?

Hello.

We have 2 ENOVIA 2022x Servers, one is for developing and testing (hereinafter, this is called "DevServer"), and another is for production("ProServer"), and connect them from CATIA V5-6R2022.

It is necessary for development team to access both server from same PC, so we tried to change config.xml for this purpose, but it failed.

[What We Did]
1. Open :\\3dx_connector\\win_b64\\reffiles\\IEFClientWorkspaceService\\config.xml
2. Change contents of tag
from https:///3dspace
to https:///3dspace
3. Restart PC.
4. Launch CATIA V5 and connect to ENOVIA.
5. CATIA is still connected to DevServer.

[What We Want]
CATIA is connected to ProServer.

Does anyone know solution?
Thank you in advance.

p.s. I apologize if another community, such as CATIA Community, is more appropriate.
