In future releases and v7 are boards with just 32mb going to no longer be supported? I have a number of RB951-2n units out with just 32mb.

I also have a hAP ac with 128mb of RAM but only 16mb of flash that appears to difficult if not impossible to update remotely to v7 without using netinstall.

I think the upgrade package is copied to RAM during the flash process, I can confirm this on hap ac2, but it has 128mb of RAM so older devices with low RAM may get bricked and require Netinstall.

v6 and v7 can be installed and upgraded on all devices. If you find any problem with storage space, it could mean your device has a hardware problem, or you have installed unsupported extra packages like Dude or User Manager (those should not be used on home routers)

I have an:
RouterBOARD 962UiGS-5HacT2HnT

It has these packages installed.
0 wireless 6.47.1
1 ppp 6.47.1
2 advanced-tools 6.47.1
3 system 6.47.1
4 dhcp 6.47.1
5 ipv6 6.47.1
6 security 6.47.1

When I copy "routeros-7.1beta1-mipsbe (1).npk" over to router and reboot I always get an error saying insufficient space and it does not install.

I just upgraded a hEX (16mb disk and 256mb ram) to v 7.1beta1 by changing the check for updates button and switching channel to development.

No problems (at least with the upgrade).

Check the flash disk on the file system. Maybe there are files there that occupy the storage necessary for .npk to install.

This is with package download and update:
