You CAN still use SysMLv1 to do Model-Based Systems Engineering! You can do MOST of what you need to do with SysMLv1.7 and you WILL be able to migrate your models to SysMLv2. Webel IT Australia offers long term SysMLv1 training and services support.

Many organisations have a long term investment in the SysMLv1 language version and project files and libraries in the Magic Cyber-Systems Engineer ^® (Cameo Systems Modeler^®) tool. Webel IT Australia will still offer training for the SysMLv1 language version for some time to come, and can help you prepare your models to make the transition to the SysMLv2 language version easier if and when you choose to. Many of the most important aspects of applying SysML to MBSE involve systems thinking and modelling strategies that apply equally to SysMLv1 and SysMLv2.
