## System Requirements

## Hardware Requirements
|
||||
|
||||
- A cheap Raspberry Pi is powerful enough for basic functionality.
|
||||
- 2 CPU cores and 1GB RAM would be the baseline for teamwork.
|
||||
- A Raspberry Pi or $5 Digital Ocean Droplet is more than enough to get you started. Some even use 64MB RAM Docker [CaaS](https://blog.docker.com/2016/02/containers-as-a-service-caas/).
|
||||
- 2 CPU cores and 512MB RAM would be the baseline for teamwork.
|
||||
- Increase CPU cores when your team size gets significantly larger, memory footprint remains low.

Hi there, thank you for using Gogs for so long!
|
||||
However, Gogs has stopped supporting auto-migration from your previously installed version.
|
||||
But the good news is, it's very easy to fix this problem!
|
||||
You can migrate your older database using a previous release, then you can upgrade to the newest version.
|
||||
|
||||
Please save following instructions to somewhere and start working:
|
||||
|
||||
- If you were using below 0.6.0 (e.g. 0.5.x), download last supported archive from following link:
|
||||
https://github.com/gogits/gogs/releases/tag/v0.7.33
|
||||
- If you were using below 0.7.0 (e.g. 0.6.x), download last supported archive from following link:
|
||||
https://github.com/gogits/gogs/releases/tag/v0.9.141
|
||||
|
||||
Once finished downloading,
|
||||
|
||||
1. Extract the archive and to upgrade steps as usual.
|
||||
2. Run it once. To verify, you should see some migration traces.
|
||||
3. Once it starts web server successfully, stop it.
|
||||
4. Now it's time to put back the release archive you originally intent to upgrade.
|
||||
5. Enjoy!

||||
|

In case you're stilling getting this notice, go through instructions again until it disappears.`)
