Can you go from a "D" to an "E": YES
What about the max pressure...
Now: Many people think they should always just run the Max Pressure, and this is ... Occasionally (Very rarley) correct.. usually you should be running less than max..
How much should you run:
This is a two step question/answer
Step one. WEIGH THE trailer, idealy you weigh each side. but if you can not do that weigh the thing as it is hooked to your tow vehicle, then while you are at it drop the jack ON THE SCALE, lift it off the tow vehicle and get another weight (GVW) just for reference, we won't be using that but it is nice to have.> Weigh it loaded as though setting out on a trip, Full fresh tank, empty waste tanks.
Now divide by number of tires (The axle (hooked up) weight.
Go to the tire maker's web site and download the tire's inflation chart
So many pounds (the results of the division) = So many PSI per the chart
That is the proper inflation.. Some folks like to add a few (up to 5) PSI, Myself among them.
