To perform migration from EMS 7.2.X (Window Server OS) to EMS 7.4.0 (Linux OS), refer to the following guide :
Migrating EMS from 7.2.3+ to 7.4.0
To migrate the EMS instance to the 7.4 Linux model, the EMS must be in version 7.2.3 and later.
Refer to the upgrade path document for more details.
To avoid any error during the migration process, ensure to follow properly the steps to migrate as per the details in the document guide.
Below are sample errors when skipping the step on the guide.
