Before we talk about a replacement, we establish whether your legacy system has to go at all.
„The system runs, but we cannot get at our figures.“
The routeKeep running it and report on it
We read the data out with our data pump HydraData and make it available on a modern database, with no write access to the legacy system and usually at times when nobody is working in it. The effort is limited to the connection and to two questions settled up front, namely how current the figures need to be and what you want to know about changes.
Fits when: If day-to-day work with the legacy system is fine and only the reporting is missing, this is often the quickest step and for some years the only one needed.
„What we want to do next cannot be built in this system any more.“
The routeReplace it fully
We read the source code, talk to your key users and decide together with them which functions belong in the new system. How long that takes depends on what you have; the range runs from a few months to more than a year, and on your side it mainly costs the time of the key users, who as a rule review a working build every two weeks.
Fits when: This applies when you keep deferring requirements because the legacy system cannot absorb them; often a failed first attempt already lies behind you at this point.
„We manage leasing or finance contracts in a fat client.“
The routeMove to vertragWerk
vertragWerk is our own web-based solution for contract administration, calculation and point of sale, grown out of the work on eLeaseWorld and MASSET. The functional core already works, the software is in beta, and pilot customers influence what gets built out next.
Fits when: This route is worth considering if your domain is that of a leasing or finance system and you do not need a fixed date for the changeover.
Which route it becomes is your decision, based on the assessment in which we read the source code and establish with your key users how far the existing system still carries you; whether that analysis runs as a separate service or feeds into a quote, we tell you beforehand.
