Knowledgebase of upgrades
I was recently speaking to a colleague of a colleague who was about to undergo a rather large migration – they were (like we have recently done) changing database technology as part of an upgrade to Gen 7.6 from a previous version.
They were interested in what experiences we had encountered when we did a similar upgrade. Of course there are the changes in data formats, different database behaviours and so on.
It became apparent that there is a need for there to be a knowledgebase of upgrades. What I mean is that using a specific function in Gen under (say DB2) on a mainfame (z/OS) will result in a different set of consideratons or behaviours when running with a different version of Gen on an Oracle database on a Unix platform. I think that this will enable upgrades to be completed easier. Does this sound a good idea ?
I think that what’s required is a matrix covering technology “from”, technology “to” and “function”…….
I’ve not explained this very well, and such a thing may even exist – if it does, can someone point it out to me ?
Rob – thanks for your comment – from what you say, do you mean that such a knowledgebase exists, or that one should exist, or that one exists solely in the experiences of EDGE members – if the latter, then what I was suggesting was a formalisation of this so that it is available to everyone in an accessible format.
This counts for different databases (e.g. timestamps) but also on platforms (windows vs J2EE). For both there must be some information available with the Edge members.
