Correcting bad/missing data

We are currently experiencing subzero temperatures and my VP2 console occasionally drops out when the temp drops below about -10F. #-o I have an extra Vue console that does not. So, there is a possibility that I may miss a morning low in the next couple of days on the main console connected to WD but have that data in the Vue console (without datalogger). I watched the YouTube video on correcting entries in the log file. Would this be all I need to do if it happens?

Thanks

yes,
and then after converting the logfile to data file then you can use the convert all logfiles (tick that) so that WD scans the logfile for new all time recors to check/set
(as long as your logfile data is OK)
