SuperChart History lost on upgrade from 0.36.4 to 0.39.4

Hi All,

I’ve been running a local server for a while now on a raspberry pi 3 for a few small projects and everything has been running great. Today I decided to upgrade from 0.36.4 to 0.39.4 and after doing so the history for my SuperCharts was lost. I don’t recall seeing any reference to this in the release notes for the versions between 0.36.4 and 0.39.4 but I could have missed it. Any idea what might have happened?

Thank you in advance,

Eric

Hello. Well… Yeah, you did a big jump and migration was removed in the latest version that preserved your history.

You need update to 0.38.0 and after that to the latest one.

If I restore from the backup folder (Blynk/backup/userxxx) will that get it back or would that cause other issues? Not a huge deal but would like to get the history back if possible.

Backup is for profile, not history. You may manually rename your binary files. You need to append “-0” to your files.

"history_" + dashId + "-0"
instead of
"history_" + dashId

That worked. Thank you!
