Re: Updating 10 year old version of entity engine and service engine.

[Paul Foxworthy]

Hi Mark,

Skip Dever had a lot to say about the issues he encountered during a move
from OFBiz 9 to 12. His experience may help you. Skip was working on this
during 2013. The earliest message I can see is here:

Cheers

Nice reference Paul. Just pasting it again. When I clicked the URL, it
didn't work, needed to copy and paste it. Giving it here again-

Hi Mark,

Yes, you are absolutely right that in past 10 years OFBiz has seen many
changes. Along with the updates to entity and service engine you are
looking for, there are other important updates you can consider. I have
been here since last 10 years and using OFBiz as the main framework to
deliver ERP solutions.

Some more background details-
There are improvements done for better performance in high traffic
environment along with support to ease of use for the OFBiz developers.

There are Security Vulnerability fixes which should also be considered for
the upgrade for sure. Here  <https://ofbiz.apache.org/download.html>you can
find more details at the bottom of the page under the heading "Security
Vulnerability".

Here is a list of OFBiz releases done after 2009.
Stable releases which are not supported by the community as of now-
10.04 (2010)
11.04 (2011)
12.04 (2012)
13.07 (2013)

Branches which are not officially released because of external JARs
licensing conflicts. Still available for download to support service
providers and developers around the world-
14.12 (2014), 15.12 (2015)

Latest stable releases- (with given URLs more details about a release can
be accessed)
16.11.01 <https://ofbiz.apache.org/release-notes-16.11.01.html> (2016),
16.11.02 <https://ofbiz.apache.org/release-notes-16.11.02.html> (2016),
16.11.03 <https://ofbiz.apache.org/release-notes-16.11.03.html> (2016)

More details - OFBiz Release History  <https://www.apache.org/dist/ofbiz/>

I know this is a very high-level information, but I hope it will be
helpful. Personally, I would recommend to analyze and learn the code and
patterns followed in latest OFBiz release and then do a gap analysis with
the implementation you want to upgrade. The gap analysis will help you
estimate the effort and plan it accordingly.

The reference given by Paul can also be helpful if you want to upgrade to
12.04 which was released in the Year 2012. There will surely be challenges
but you can put your questions on user mailing and move forward.

HTH.
