Please note that Home Assistant is officially supported on Raspberry Pi 4 and 5 with 2GB of RAM minimum Raspberry Pi - Home Assistant
If your older rpi is for instance a rpi 3 with 512MB of RAM, I'm not sure it's going to cut it.
Huh, I'm running it on a rpi 3B which was (barely) supported when I installed Home Assistant on it. It has only 1GB of memory but it's still working very well! I don't have a ton of automations though
Can confirm: Using a rpi4 with 2GB for a long time worked well.
