How do I convince someone to migrate from the AS/400?

Thanks. We'll let you know when a new response is added.

I don’t want to sound flippant or rude, so please accept my apologies if it comes across that way.

The first thing is to ask yourself why do you want to migrate away from it. If you have reasons that are more than just a personal preference or ambition then you need to quantify those in terms of what’s to be gained by moving and what’s lost by staying.

After that you need to do the same exercise with what you want to migrate to.

Personally I couldn’t think of a good reason to move away from the AS/400, iSeries of System i5 to another platform – although the business might think otherwise.

Best regards

Nothing to improve is answer…. just 100% agree with it…

There are great reasons to keep the code and migrate to another OS like Linux and run the apps on X series blades that are virtualized. You can’t use VMWare on i OS. That means you can’t get dynamic allocation and you can ‘t get on board fast cheap High Availablility. HA costs a fortune for i os and you need to buy a lot of expensive hardware. You could just run your RPG or COBOL applications on LInux on cheap X Series blades using the same DB. if you migrated the code to Linux or AIX. The DB2 fees are crazy expensive and so is the cost of i OS.

    So you can't think of a good reason to give someone to migrate away from AS/400? I think that says it all...:^)

    AS400 is an excellent platform, stable and secure but small shops can not afford it. So in this era when there are many cheaper options, migrate from AS400 could be an alternative to some companies. Other reasons could be addressed such as hosting a specific application that doesn't run under system i environment, the lack of a personnel, etc.

    Hi, I think you need to look at what you currently use the machine for and what else is available to achieve the same (or preferably more). The AS400 is already there, so there's a certain amount of maintenance costs associated with it and maybe lease costs if it's on lease. If you look to migrating to something else then you will have the initial costs of new hardware and software and possibly re-training costs. You need to assess which is going to be the cheapest option (migrating or not) not only short term, but also long term? You also need to look at possibilities of migrating your existing data and the cost of doing this. There are certainly reasons to give for migrating (lack of support or functionality in current applications for instance), but there are equally as many if not more reasons to give for not migrating (uncertainty of whether a new application will do exactly what you want - Don't believe everything the sales people tell you). Regards, Martin Gilbert.

    Hi, Don't forget when looking at any options to look to see what "hidden" costs you're going to end up paying. The AS/400 is pretty much all-inclusive, whereas some of the seemingly cheaper options will need third party software for development work, communications, databases, etc. Pay attention to the interoperability/compatibility between these third party offerings, to avoid getting a machine that runs several different applications which can't share any data. (of course it's also possible to get into this situation on an AS/400, but less likely). Regards, Martin Gilbert.

    Hello Cgoodin, It might help us to know the reasons why you would want to convince someone about migrating from the AS/400, there might be your argument. The only reason why I recommend someone to get rid of an AS/400 is that the application you need is a non bussiness app. :-) There are a lot of nightmare stories of companies that tried to migrate, so you must be sure you cover all the bases before trying to convince somebody. Just my two cents. Best regards,

    Good point GAC, Is it from a financial point of view / technical point of view / some other reason that you want to convince them to migrate? Regards, Martin Gilbert.

    well i'm trying to convince "them" to migrate to an HP integrity as HP has partnered with Infinite software to move over the apps... my challenges are keeping pace with new technologies, user interface, ect.

    Hi, If you've already got something arranged to move over the apps, then the decision is already made isn't it? Regards, Martin Gilbert.

    You can use Infinite iSeries to recompile AS/400-based applications to Linux, Windows or Unix. There is now a free download for the iSeries to Linux version for RPG-based applications.

    Why in the world would you want to downgrade to HP? I can't think of any platform that has the reliability, scalability, and security of the i5, least of all a wintel solution.

    Hmm... I understand that the initial outlay may put people off. IBM i (AS/400) is not cheap to buy into, however the overall cost of ownership over 3 years (say) can be much less - no DBA headcount to speak of, no complex systems management, almost no downtime, super reliability. Because the DB is integrated in the OS there's no separation of skillsets. We run an expensive machine with 300 users but the expense includes the OS and DB2, we only have one person at any one time with responsibility for supporting it, and he/she doesn't have a lot to do and generally gets on with other things (like supporting and rebooting peripheral Windows servers). No tablespaces, complex connection strategies, and it just plain works. Incidentally there are smaller IBM i editions nowadays that are supposed to compete price-wise. I can't say whether they do, though...

    Gentlemen, This is a discussion from August 2008. Do you think that is still actual? I don't. YuVa47

    I've yet to know of a company that's migrated from the AS/400 in the interest of "keeping pace with new technologies, user interface, ect." that hasn't regretted the bejeesus out of it.

    Find the exact statement that the Coca-Cola marketing chump used to sell "New Coke" to his superiors. Take that statement and replace every instance of "Coke Classic" with "IBM i" or "AS/400". Similarly, replace each occurence of "New Coke" with "HP". That should do the trick. ;-)

    YuVa47, as this comes up frequently it would seem the topic is germane even if the original question is a bit dated.
