I'm a Spring newbie so if this is wrong forum let me know. I've inherited a java web app that is about 12 years old. It is a propietary 'framework'. At some point Spring 1.9 was included and used only for IoC/DI. I would like to bring it into the proper century (2.5 or 3.x). Unfortunately, I can not convert everything at once and then retest. Is there anyway to run two different versions of Spring simultaneously?
Namely I want to:
1. Develop new Web app functionality with Spring MVC and Spring SQL.
2. Have the old proprietary functionality continue with IoC/DI with 1.9.
3. Possibly migrate old functionality to new version as required. (This will be a low volume activity).
Can anyone elucidate or point me in an appropriate direction?
Thanks in advance!
