If you have the ColdBox Platform Utilities installed for CF Builder, there’s a ColdSpring converter built in. You should be able to right-click on your XML file and generate a WireBox mapping file.
It’s worth noting that WireBox allows you to be less verbose and reference your models via convention with scan locations and specify persistence attributes through component metadata. That being said, I think Luis typically creates mappings for his module’s models to ensure they’re unique in a format similar to “module@ModelID”.
How complicated is it to convert Coldspring to wirebox? I never used it alone, only with Mura where it is quite slow.
