```
env ABI=FreeBSD:15:amd64 IGNORE_OSVERSION=yes pkg -c /mnt/upgrade/ install -r FreeBSD-base FreeBSD-pkg-bootstrap
```
Then upgrade the base packages
```
env ABI=FreeBSD:15:amd64 IGNORE_OSVERSION=yes pkg -c /mnt/upgrade/ upgrade -r FreeBSD-base
```
Check, if FreeBSD-set-base is installed:
```
env ABI=FreeBSD:15:amd64 IGNORE_OSVERSION=yes pkg -c /mnt/upgrade/ install -r FreeBSD-base FreeBSD-set-base
```
upgrade all other packages
```
env ABI=FreeBSD:15:amd64 IGNORE_OSVERSION=yes pkg -c /mnt/upgrade/ upgrade
```
Temporarily activate boot env and reboot
```
bectl activate -t 15.0
shutdown -r now
