Hi,
We are in the process of upgrading from 9.1e version (32bit) to open edge 10.02B (64 bit). At this point in time we have made the appropriate changes to our code to remove deprecated features and are currently testing our application. Before we upgrade our production environment i had a few questions / concerns for which i would need to seek help from this forum.
a) What kind of rollback strategies can be employed while performing the above upgrade? I am aware of initial backup (9.1e) or dump and load but is there any thing else which can be considered and which would be faster without losing transactions. Because once migrated to open edge and we face any issues after around 3 weeks it will then become almost impossible to go back to 9.1 e without dump and load. Is there anything else we can do to mitigate the risks ?
b) I do understand that moving from a 32bit version to 64 bit will help enhance application / database performance (by tuning the appropriate params) are there any drawbacks specific to performance or any other items which we would need to test prior our production move. I believe this was tried earlier in our 9.1d version but somehow we did not proceed. Hence i am lil skeptical of how this would behave.
All your inputs on this will be highly appreciated.
Thanks,
Sekar
