How to migrate from Plesk

1. In order for the server to run efficiently with ispmanager, it is important to ensure that the recommended software is installed. The verification and installation process is as follows:

Configure the recommended software. Go to Settings section and select Software Configuration.

Ensure that the following components are enabled:

• Web-server (WWW) - a web server configured in a similar or compatible configuration is mandatory;

• Mail server - is required to process mail on the server;

• Name server (DNS) - It is recommended to use PowerDNS for efficient management of DNS records. This is especially recommended if the server hosts many sites;

• FTP server - provides the ability to transfer files to the server using FTP protocol;

• DBMS (database management system) server - needed to store and manage databases on the server;

• PHP versions - make sure that you have the necessary versions of PHP installed to support your applications and scripts;

• Optional software for compatibility - Install additional software to ensure compatibility with other system components, if necessary.

2.  If you are using Cloudlinux, it is recommended to see the description  of the panel operation in this operating system.  

3. For successful import to the server, it is necessary to provide a reserve of free disk space five times larger than the size of the archive to be imported for a given user.

4. During import, it is recommended to disable password complexity checking in the System settings section.

5. To successfully import databases for the DBMS on a server with ispmanager, make sure that the default-authentication-plugin=mysql_native_password parameter is set in the configuration file. Use the following command to verify that this parameter is set:

grep -ir "default-authentication-plugin" /etc/
