WeatherCat on Big Sur on M1 Data Migration

[Stevev1000]

I just updated from a 2010 IMac on High Sierra to a new M1 Mini On Big Sur. The Apple Migration did not work for me , so I started new and restored some files from a Time Machine Backup.

My question is because I already installed WC  on the new Mini and have about 2 weeks worth of data. How can I copy in my old data from my IMAC. Can I just stop WC and copy the directories described in other topics and restart WC. Won’t that overwrite  the current open data file , or can that file be edited and can I paste in my readings from the beginning of January?

I also have a USB attached Vantage Vue , and I am using the updated silicon labs driver.

Our Wiki has an article that explains how to migrate your WC installation from your iMac to your Mini.

Steve1000: Thank you for asking this question in the forums. I had a similar problem with an Intel MacBook Pro after an upgrade to Big Sur. After much effort, I downgraded back to Mojave, where my Davis Vantage Pro 2 Plus is working just fine again. But I didn't want to lose 7 years of data!

Blicj11: Thank you very much for the reference to the wiki item. Worked great for me!

Dear Scrib and WeatherCat faithful,

Obviously, you have been on the forum for a while, but since this is your first posting, let me officially welcome you to the WeatherCat forum!

I'm glad that you were able to get your system up and running after much hardship.  It is an important cautionary tale.  Your Mac running WeatherCat isn't simply a computer, it is the archive of all your weather data.  Most of us really care about our data, so I strongly urge anyone considering an upgrade to check first on the forum to see if it is safe.  Delaying an update is a small price to pay for keeping all your data secure.

That's what makes the WeatherCat forum great!  We all help one another!   

Cheers, Edouard
