It will "probably" work but you may hit issues building patches. Nothing specific comes to mind. If you hit issue, you can upgrade using latest toolset then start patching again.
Generally speaking, one should not change tooling when patching. That goes for all tools, versions of Visual Studio, compilers, etc. Too much churn can occur. _____________________________________________________________ Short replies here.

Subject: Re: [WiX-users] Patches no longer working for a specific RTM using WiX 3.7 + Pure WiX Patching Sorry, posted that last one to the wrong conversation :( Rob et. al. I have a question regarding upgrading WiX. We have several RTMs that have been produced using 3.7 and 3.9. Is it "supported" to move producing updated installers+patches to newer versions of WiX? My concern is that I don't want to have a large number of WiX versions floating around as both WiX and our own products mature over time.
