You can expect some because 11.04.06 is years old and there were a lot of changes.
Personally, I would go with the 14.12.01 release branch, it's stabilizing and you don't have to do as much upgrade work later.
I can't say much about BigFish but I assume that it is located in the hot-deploy folder as well and the update instruction assumes you only have BigFish installed. Just keep your own extensions.
Hope that helps, Michael Michael Brohl ecomify GmbH www.ecomify.de Am 12.10.15 um 09:01 schrieb Barou:
I am experimenting with ofbiz for some weeks now I have done some coding in Apache apache-ofbiz-11.04.06. I want to know if I can upgrade it to OFBiz 13.07.02. As I am experimenting I came a cross to an implementation of ofbiz called BigFish. But when I look at how that also can be upgrade from one version to an other is not very practical. http://bigfish.solveda.com/bfDownload.html specifically this point : Update existing instance Instructions:Delete "hot-deploy" directory from the INSTALL-DIRECTORY. Also delete *INSTALL-DIRECTORY*\themes\osafe_theme. I am not ofbiz expert but if I delete my hot-deploy directory I will delete all my own extension. Can some body clarified to me how I upgrade ofbiz from one version to a higher version ?
