Back in version 1.12.2, Thermal Expansion featured "Conversion Kits." Instead of applying all upgrades sequentially to a machine, it allowed you to upgrade the machine to the desired tier in one go.
This mod does the same thing for the Mekanism. Instead of using the Basic, Advanced, Elite, and Ultimate tier installers one by one, you can upgrade your machine to the Ultimate level in one go with the Ultimate Conversion Upgrade.
The mod also includes Elite and Advanced Conversion Installers.
