My two 5920AFs have 256MB flash, dir reports 258048 KB total with 171328 KB free. 2 times the R2432P03 fw is 173056 KB. The logfile is disabled and empty.
No other unecessary file that can be permanently deleted (not just trashed, so using the delete /unreserved CLI Command instead of the more common delete which admits the undelete) to free up less than 3 MBytes you need? can you post the output of dir (and dir slot2#flash/: to see Standby IRF Member's flash space status) CLI command?
So my understanding is that I need to upgrade using the bin-files instead of the ipe-file, but how do I extract the bin-files from the ipe ?
Good question.
Basically bin files and ipe file are the same thing from the point of view of the Switch operating system (the ipe file is a package that contain Boot ROM, boot and system bin files that are decompressed [**] - so it is a package that contain compressed files - by the Switch during the upgrade procedure...indeed you need at least two times the ipe file's size as flash free space because the flash needs to store the ipe file and both its decompressed content, the boot/system bin files)...AFAIK decompressing an ipe file is an operation that happen at Switch's operating system level...I'm not sure - just a personal guess - you can perform that externally (like unzipping a zipped archive) to obtain boot/system bin files separately for your convenience...but I could be wrong about that (and I don't have all the informations HPE has internally with that regard). Some Software are published on both forms: ipe plus separate bin files, other Software is published only as ipe file.
I am not really comfortable removing the running version of the firmware until I have verified that the new version works.

Yeah, first of all you shall perform a Compatible ISSU on your IRF (see Release Notes and this HPE Knowledge Article)...and that is a good thing to start with...then...there should be a way to safely free up space [*] without exposing your IRF at any risk carried by a reboot.
[*] The statements are: "For the switch to start up correctly, do not delete the main startup software images when you free storage space before upgrading Boot ROM. On the Boot menu, the main startup software images are marked with an asterisk (*)." (files marked with an (*) are generally system.bin, boot.bin and startup.cfg) and "To avoid data loss, do not delete the current configuration file. For information about the current configuration file, use the display startup command.".
[**] not totally sure about that...IMHO the ipe file is just an archive (with a special format than should contain some Header information) used to safely transport bin files...so no real compression takes place, it's just a (de)archive operation performed by the Switch with Header check to validate ipe file contents.
A thought: why not using USB Stick to move back and forth current boot/system bin files (move them on USB, erase them from flash:/ and slot2#flash:/, free space should be available, transfer ipe file and decompress then, before any reboot - so you should answer "N" to the question "Upgrading software images to compatible versions. Continue? [Y/N]:" to avoid reboot after bin files were depackaged into slot2#flash:/ (remember that Standby IRF Member should reboot first in case of Compatible ISSU procedure) - doing things that way you can then remove ipe file (you have both new bin files on the slot2#flash:/ as you wanted) and finally move back from USB Stick the old system and boot bin files...once done perform reboot as requested.
A second thought: probably there is a second way to obtain bin files from the ipe file...using the boot-loader command, but you need to have, as usual, free space on a IRF Member to play with (brave men play against the free-space problem deleting actual bin files - they are in RAM, isn't it? - without rebooting).
