upgrade from 2.70 to latest version

Either you missed an upgrade script, or there were errors when you ran one.

The "Leased..." fields are in table ScheduledTask
The "Company..." fields are in table Store

yes.. So, do I have to add these fields in database?

Yes, but you may want to find the script that should have done it and re-run just those specific "...add column" lines

I was thinking the same that why the DB script didn't added these columns? I only got following messages in output.

Caution: Changing any part of an object name could break scripts and stored procedures.

Those are just warnings and should not be related.  Is it possible you missed a script?

Is i fine if I upgrade all scripts one by one for DB and then run the project and solve errors if any?

i.e. after running all upgrade scripts, I add project files of latest version only directly, is that ok?

OR..

will it be better that I install the latest version of nopCommerce and migrate my database to this new empty database? will it be easier?
