I was trying to update my pihole using the "sudo pihole -up" command, but after fetching the lists, an error came back stating that there wasn't enough space to install the updates. I tried again and it successfully went though. I then did "df -h" only to see that I had 800kb of space left of my 4gb SD card. Clearing up the cache freed it up to 1.2mb, but that is still obviously not a lot of space for head room.
Is there any way to transfer pihole to another larger sized SD card without reinstalling everything? Or should I just reinstall it and import the settings using the teleporter? It's going on the exact same raspberry pi.
