This may be due to multiple applications pointing to the same physical path, as explained in more detail in this comment: https://github.com/Azure/App-Service-Migration-Tool/issues/3#issuecomment-474005747 Could you please let us know if you think that is not the case for your server? We are looking at long term solutions to this type of case to not only improve this error experience but to actually enable you to still do a migration, but don't have a timeline for this yet.

We have released a new Preview version of Migration Assistant today that should help address this class of issues. We would appreciate if you gave this update (in Preview) a try and let us know if this works for your scenario. Thanks

I got the same error here: TypeError: Cannot read property 'split' of undefined

The server I'm running the Migration Assistant has 12 applications. Is there any workaround? Thanks.

Hello @Frontarolli This is due to a dependency on .NET Framework 4.7.2. We are fixing this error message to be more actionable (as well as making it more clear on the Migration Assistant page that this is a requirement). The way to work around this is to install .NET framework 4.7.2 runtime on the machine (such as from here: https://support.microsoft.com/en-us/help/4054530/microsoft-net-framework-4-7-2-offline-installer-for-windows). Apologies for the inconvenience, Kristina
