I have uninstalled version 3.7.2 before i install the newest version of KNIME. Some of my workflows were in default workflow folder and i have also a lot of extensions which i am using for different purposes.(Training, test, performance)
I have a suggestion by installation of KNIME 4 which will be great. It should ask to me whether i want to keep my workflows in knime default or preferred folder. May be on second screen it also should ask me whether i want to keep my community extensions if those are available or compatible in newest version.
After i have uninstalled the 3.7.2, the workflows which i have created for example and learn purposes, they all gone. and also my extensions were also gone. of course i am keeping my important workflows in our server. For extensions i have to install all of them.
Thank you again for the newest version.
