Preparing for Migration

Before you start migrating from WebHosting Linux to WebHosting Plesk, you need to do the following:

1. Install and configure the WebHosting Plesk module for Odin Automation or CloudBlue Commerce, as described in WebHosting Plesk Provider's Guide > Deploying the WebHosting Plesk Module.
2. Add Linux-based service nodes and install license keys for them, as described in WebHosting Plesk Provider's Guide > Apache Nodes with MySQL.

3. Register the PostgreSQL Server and MySQL database servers used by the WebHosting Linux module in WebHosting Plesk, as described in WebHosting Plesk Provider's Guide > Dedicated Database Nodes> Attach an existing database server.

   Important: Pay attention to the case in which the database host names are written. They are case-sensitive. That is, if you had a database host name MyExampleDatabase.Example.com, be sure to register the database server with WebHosting Plesk exactly in this case: MyExampleDatabase.Example.com.

4. Make sure that network connections can be established between WebHosting Plesk service nodes and database servers used by WebHosting Linux.

   
   After that, change the settings of the target WebHosting Plesk service template: Go to Provider Panel > Products > Service Templates > template name > Database Hosting tab > Edit, and select either Any shared database server or Selected shared database server, and specify the SQL server that you registered earlier in this step.

   Note: If you do not register database servers with WebHosting Plesk before migration, database servers will be registered automatically, but users will not be able to create new databases on them.

5. If subscriptions in WebHosting Linux use exclusive IP addresses and these IP addresses must remain exclusive after migration, set up a new range of exclusive IP addresses in Odin Automation or CloudBlue Commerce and assign them to WebHosting Plesk nodes, as described in WebHosting Plesk Provider's Guide > Allocating Dedicated IP Addresses to Service Nodes. The number of new exclusive IP addresses must not be less than the number of IP addresses used in WebHosting Linux.
6. Make sure that connections to the port 29443 are allowed on Plesk service nodes, and that Plesk service nodes are accessible from the Odin Automation or CloudBlue management node.
7. Configure service templates and service plans.
