I am very glad with the nice CiviCRM! This is an perfect online CRM-system!
After a lot years now, i would like to upgrade to the current version. But i am very scared if it would work.. The Current version: CiviCRM 4.6.20. is upgraded from an earlier version, and that was also with a lot of errors..
Does someone know how to do this the best way. There is very much information in the system, if there is something going wrong, it is a very big problem...
What is the best way to install a new version, and get all the data from the old.
Thanks a lot.
With Kind Regards, Mark
