So our local city / county governments are about to consolidate and an interesting situation has arisen.
The County is a full ISS / ASP.net shop while The City is a full L.A.M.P. / Drupal organization. The County has hundreds of custom built asp pages and does not want to use a CMS as they prefer to build their own and keep their code in-house. The City on the other hand uses a LAMP / Drupal CMS setup as they prefer to build and develop in an OSS model.
Neither of the two want to budge or give with regards to their platform.
I've done some research in seeing what is better and you can always find experts from both sides citing examples of their benchmarks and how what they use is better.
I have been a long-time lurker here and figured this might be a great place to discuss such an issue.
Has anyone been involved in a merger such as this? What solution did you go with? What reasons were given for adopting said solution.
