 ## Recommended migration plan
 
 Each organization will have different metrics of success and internal migration processes. This section provides suggested guidance to consider when migrating from the Log Analytics MMA/OMS agent to the AMA, specifically for Microsoft Sentinel.

 Many networking and security devices and appliances send their system logs over the Syslog protocol in a specialized format known as Common Event Format (CEF). This format includes more information than the standard Syslog format, and it presents the information in a parsed key-value arrangement. The Log Analytics Agent accepts CEF logs and formats them especially for use with Microsoft Sentinel, before forwarding them on to your Microsoft Sentinel workspace.

 Many applications log data to text files instead of standard logging services like Windows Event log or Syslog. You can use the Log Analytics agent to collect data in text files of nonstandard formats from both Windows and Linux computers. Once collected, you can either parse the data into individual fields in your queries or extract the data during collection to individual fields.

 **Syslog** is an event logging protocol that is common to Linux. You can use the Syslog daemon built into Linux devices and appliances to collect local events of the types you specify, and have it send those events to Microsoft Sentinel using the **Log Analytics agent for Linux** (formerly known as the OMS agent).

 ## Architecture
 
 When the Log Analytics agent is installed on your VM or appliance, the installation script configures the local Syslog daemon to forward messages to the agent on UDP port 25224. After receiving the messages, the agent sends them to your Log Analytics workspace over HTTPS, where they are ingested into the Syslog table in **Microsoft Sentinel > Logs**.
