Hello,
our Customers are currently using Sybase SQL Anywhere 8.0.3
and we want to upgrade all of them to Sybase SQL Anywhere 10
or 11.
We are currently searching for an Upgrade-Procedure with
minimal downtime for our customers.
Is there are possible way with Replication for example to
perform the upgrade while a second database is still online?
What is the recommended procedure to do the upgrade?

Thanks, Mischa

Mischa,

I would suggest to raise this topic in the replication newsgroup, i.e.
sybase.public.sqlanywhere.replication.
That will be monitored by many more people.

Regards
Volker

Mischa,

This very much depends on the type of application that you have.
As we have applications that mainly access the databases in read mode, we
made the old database inaccessible to users, copied it, and made it live
again, and then did the upgrade (reload and application upgrade) on
another server. Finally, the new application was made live during another
short downtime.
Users were informed that the few write accesses that they did in the
application in the meantime would be lost.

Frank

Hi Frank,
unfortunately we need to write into the database. At the
moment we plan to make an automatic process, which runs in
the night and upgrades the database. But we have some
customers which require minimal downtime even in during the
night.
