How realistic is it to upgrade a very old version to the current version?

[kevinblo]

I have installed 3.9.2 version.

Do I have to go through all the releases one by one up to the current one?

Thank you.

Hello @kevinblo

Version 3.9.2 has the same upgrade system as the current version. And system requirements haven't really changed since.

You can review the upgrade instructions for each release since v3.9.2:

It should read:

Simply overwrite the old files.

As far as I remember, there as not been any other instruction, but I am not 100% sure.

I would advise:

1. Backup your files
2. Backup your database
3. Download latest version
4. Copy the new files over the old ones
5. Access RosarioSIS

If there are no SQL errors, then you are good.
