You have to convert from the matching grandMA2 version to get the most up-to-date functionality. So convert from grandMA2 v3.9.60.38 into grandMA3 v1.7.2.2. When you do so, the following information will get converted:
Patch and Fixture Types
Worlds
Filters
Groups
Presets (only value layer, not timing or effect layers)
Sequences (only value and timing layer, no effect layer), including settings (where possible)
Selective Effect Objects (converted into selective presets in All Pool 2 / Preset 22.*)
