We are planning to upgrade the intergration server version 6.5 to 7.1.2 as of now.
Because my client is has the lincense of 7.1.2 only.
Currently we are using only WM components Developer & Integration server
We have around 50 interfaces and all the transactions related to FTP only. (means source is FTP & target in FTP)
and storing audit & error logs in file systems only.
Please advise me the approache (side by side migration (or) upgrade over exising version) to complete the migration faster.
As per the WM documentation (6.5 to 7.1.2) , I found only 5 WM built in services (are deprecated) which are using in our project.
