I liked not having to track CTC/CNC pairs any more. At a previous shop the migration was seamless, however... - We moved from shared ESCON channels. From experience, dedicated ESCON (or 3088) migration to shared FICON CTCs are more involved. If you are on dedicated paths, take the time and effort to understand and implement shared CTCs. I took a page from a colleagues' playbook and drew a chart for the migrations. Adding in devices later was much easier with established numbering conventions. Pay particular attention to CUADD on your CTC control units. - We had FICON directors to run the FCTC channels through. If you have more than one CEC, especially if you are connecting across buildings, FICON directors are worth consideration for redundancy and bandwidth. While directors also enable you to share FCTC channels with other devices, I wouldn't recommend piggy-backing XCF CTCs with other devices. - Obtain and read the "FICON Planning and Implementation Guide" Redbook: http://www.redbooks.ibm.com/abstracts/sg246497.html?Open There is a FICON CTC RedPaper, but it's over 10 years old, and hopefully incorporated into the Redbook.
