Upgrade joomla3 to joomla4

Hi I have in plan to upgrade my Joomla v3 to v4
What is a procedure with the ConatctEnhaced component in the upgrade process?
Thank you

Dear Komir,

I usually create a staging subdirectory or subdomain, duplicate the site, then move to the main domain or main directory. This avoids any downtime.

Joomla and Contact Enhanced upgrade procedure;
1. Create a backup;
2. Before Joomla Upgrade you might have to disable (not uninstall) Contact Enhanced and its extensions;
3. Upgrade Joomla;
4. Download the latest Contact Enhanced version and upgrade to Contact Enhanced 4.0 or newer;
5. Enable Contact Enhanced component and its extensions;
6. Review & Save Contact Enhanced Options;
7. Review & Save Menu Items;

Optional steps:
8. Contact Enhanced new version has totally refactored the Template System, if you had a custom template you'll have to create it again because it isn't compatible with the latest Contact Enhanced version;
9. Some Form Fields have changed and they should be converted to the new format, but it's always good to check their respective forms to make sure they are alright;
10. Check all menu items, modules, and plugins you use;

Let me know if you have any further questions.

Best regards,

Thank you
I followed your instruction
After installation of the latest Contact Enhanced Joomla4 version get a message like a screenshot attached

I have installed pkg_contactenhanced-4.0.3.2-pro version

and PHP8.1

Dear Komir,

I couldn't reproduce this issue locally.
Can you provide Joomla and FTP access to your staging website, so I can take a closer look?
You can send the credentials via the Support > Contact Form.

Best regards,

Send you credentials

Thank you Komir.

I've already fixed and replied to your email this morning.

Please disable the credentials you've created for me.

Best regards,

Thank you
I looked now and see Contact look weird in administration and contact is not visible in fronted

Also, I noticed, when enabling "System - Mail Links to Contact Enhanced (Mailto2CE)" in front of articles has "404
