wix - ADDLOCAL=FEATURE1 in MSI installer removes other FEATURES

Question

I am trying install one of FEATURE_NEW using wix installer setup.exe(2.0) on top of setup.exe(1.0) setup.exe /v /qn ADDLOCAL=FEATURE_NEW

It installs FEATURE_NEW, but issue is, it removes other features FEATURE1,FEATURE2 etc.

I want existing feature should upgrade and new FEATURE_NEW installed, no additional FEATURES should be installed.

So my question is Can I Install/upgrade product with previously installed feature list 'N' plus newly added feature i.e. N + NEW_FEATURES. I am searching something like,

setup.exe /v /qn ADDLOCAL=INSTALLED_FEATURES,FEATURE_NEW

If you are doing an ADDLOCAL then you are explicitly listing the features you want to install - the installed features are what you specify. It is not incremental, and does not mean "also install these features". For example, it turns off feature conditions. If you want to add features during a major upgrade with a bootstrapper you can use MsiEumFeatures() to get the installed feature list, to which you add your new ones. Another way would be to use a custom action to parse the ADDLOCAL string, sequenced after MigrateFeatureStates, and add the new one to the list.
