When deploying a Salesforce Maps solution, there are three considerations an admin should take:
A) Train users before they go into the production org. This is a best practice for any Salesforce implementation project, as it helps to prepare the users for the new features and functionalities, and ensure a smooth adoption and transition. Training can include hands-on exercises, demos, videos, guides, and quizzes to test the users' knowledge and skills1.
C) Make sure permission sets for users and profiles are maintained and migrated. This is important to ensure that the users have the appropriate access and visibility to the Salesforce Maps features and data, such as layers, routes, schedules, territories, and live tracking. Permission sets can be created and assigned to users or profiles based on their roles and responsibilities2. Permission sets can also be migrated from one org to another using change sets or other deployment tools3.
D) Get provisions of all the appropriate licenses. This is essential to enable the users to use Salesforce Maps in their org. There are different types of licenses for Salesforce Maps, such as Maps User License, Maps Live User License, Maps Mobile User License, and Maps Territory Planning User License. Each license grants access to different features and functionalities of Salesforce Maps4. The admin should request the appropriate number and type of licenses from Salesforce before deploying the solution.

Automatic route re-optimization is a feature that requires purchasing Salesforce Maps Advanced. This feature allows users to automatically adjust their routes based on real-time traffic conditions, customer availability, and other factors. This feature can help users save time, fuel, and money by finding the most efficient routes for their visits. This feature is explained in the Salesforce Maps Products document.

Routes is the feature that supports the use of Custom Drive Profiles. Custom Drive Profiles are used to create routes that are optimized for trucks and other vehicles that might not be able to travel the same roads as passenger cars3. A route can be optimized based on the specific characteristics of a truck and its cargo, such as height, weight, length, and hazardous materials3. To use this feature, the user needs to create a Salesforce Maps Drive Profiles tab and a custom object for Maps Drive Profile3. Then, the user can create a new Drive Profile with the details of the vehicle and select it when creating a route in Salesforce Maps3. The characteristics of the vehicle's Drive Profile will be used to create a route that is compliant with published permanent road restrictions3. Favorite Location, Schedule, and Marker Layer are not features that support the use of Custom Drive Profiles.

A user can plot a Live Layer in Maps for three main purposes. One is to dispatch the nearest driver to a service call, which can help optimize routing and scheduling. Another is to validate a driver's location in the event of an emergency, which can help ensure safety and security. A third is to see any occurrences of speeding events for a given Live Asset, which can help monitor performance and compliance. These purposes are explained in the Create Live Layers document.

Because Salesforce Maps is an installed package, its data and configurations cannot be moved via change sets. Change sets can only move metadata components between orgs, not data records or custom settings. Therefore, the Maps Administrator should consider recreating the Salesforce Maps data and configurations by hand in the destination org, or using a third-party tool or API to automate the process. This is explained in the Salesforce Maps Apex Developer Guide.
