Navionics Ipad Chart Transfer?

[torrmundi]

Now that my subscription for USA, S America & Caribbean have expired, and I've moved to a new Ipad, the old charts that I should have had access to are unavailable.

Has anyone transferred downloaded charts from one device to another? If so, how?

This is a temporary move; now that Garmin has scr*wded their customers by reneging on the terms of previous purchases, I'll be heading for the exit. Aquamap & Luckgrib on Ipad for me, and OpenCPN on Windows. Navionics is a dead deal now.
