Firmware update to IPC-HFW2531T-ZAS

[jaes]

Hi,
I'm real beginner with these cameras and asked new firmware from Dahua because now it's very old (2017). They send me bunch of firmware's (try those...)
Should I update cameras in chronological order (starting with oldest) or just straight from newest (highlighted)?

Try the 2018 version.

At first or just that?

this one

Not newer after updating with that?

If can't update it still show the old version.

I mean that after updating to version 18, should I update to next one (21)? And then to version 24?
