How to add cpu core

There are two ways to do this :-

1. Upgrade the Instance Type: You can stop the current EC2 instance, change its instance type to one with more CPU cores, and then start it again. To do this: Stop the EC2 instance from the AWS Management Console. Navigate to the instance details, click on "Actions", then select "Instance Settings" > "Change Instance Type". Choose an instance type that offers more CPU cores. Start the instance again.

2. Migrate to a New Instance:Alternatively, you can create a new EC2 instance with an instance type that has more CPU cores, install the required Linux OS version, and then migrate your 3CX installation to the new instance. Here's a general outline of the steps: Launch a new EC2 instance with the desired instance type and the latest supported Linux OS version. Install and configure the 3CX software on the new instance. Backup your data from the existing 3CX installation (such as configuration settings, call recordings, etc.). Restore the backup data to the new instance. Update any DNS or network configurations to point to the new instance. Test the functionality of the 3CX installation on the new instance to ensure everything is working as expected. Once validated, you can decommission the old EC2 instance.

Before proceeding with any of these options, it's important to ensure that the new instance type you choose meets the requirements of the 3CX software and any other applications running on the server. Additionally, make sure to take proper backups of your data before making any changes to avoid data loss.
