<p class="MsoNormal">First of all, PROJ 7 can read ct2 files so you don’t have to convert them. But of course the GTG is a better format so I would encourage you to do so. What files are you trying to convert? All the grid files that you have previously submitted
to proj-datumgrid have all been converted to GTG as you can see here: <a href="https://github.com/OSGeo/PROJ-data/tree/master/is_lmi">

<p class="MsoNormal" style="margin-left:36.0pt">For Proj7 all grids must be transformed to GTG format. We have two grids in .ct2 format<o:p></o:p></p>
