1.3.1. Purpose¶

　This edition is prepared for customers using Acronis version 11.5 or 11.7 with a local configuration (Windows server or Linux server and agent only).
　We recommend acquiring backup of the server before upgrading.

Note

Acronis version 12.5 cannot be used only with an agent so that it is necessary to implement management server functions along with upgrading of the agent.

Note

　Please check resources of the server before upgrading. System requirements are as follows.
