Just install the new one without removing the old one. In most cases, two running at the same time don't fight each other, as antivirus software tends to do. Password managers are a companionable lot, not like antivirus tools. Here are two ways to make the switch from your old, tired password manager to a slick, powerful new one. Changing to a new password manager isn't a walk in the park, but neither is it impossible.
If your password manager is mired in the past, you don't have to be a stick-in-the-mud. For example, about seven years elapsed between RoboForm version 6 and version 7, and another six to reach the thoroughly up-to-date RoboForm Everywhere version 8. Some update frequently, adding features like password inheritance and automated password change. We constantly review the latest password managers as they grow and evolve.
