Paid module updates

[A. Smith]

I'm eligible for several paid updates, for example NA27-GBS to NA27-T. It's cheeper because I also own GNT-T. My question is, will this upgrade replace both GNT-T and NA27-GBS?

No modules are removed when you upgrade to a paid upgrade, but if the new module actually supersedes the old, you will no longer be able to Easy Install the old while the new is installed. In this case GNT-T would not be superseded, but NA27-GBS, which is untagged, should be.
