We have many customers who have switched to THERMS from other competitor software - The strategy that seems to work the best in these situations where your operations are running on and your staff are comfortable with the old system is to incrementally move to THERMS.
Make sure you management and supervisors are familiar with THERMS by creating and testing out features with a “Location” in your account named something similar to “Training Location”.
Pick a handful of your field managers/supervisors who work regular shifts and have them be the first wave of User’s in your team to use THERMS for shift work so that they can become the go-to experts for the rest of your staff.
If you have patrol and static guard divisions, you might want to incrementally onboard your static guard shifts for 1 week then following the small learning curve, switch your patrol division over to using THERMS for shift work (or visa versa, patrol first then static guards).
