It is (almost) never possible to restore an ontape archive from one
version of IDS to another, even down to restoring between different Ux
levels.
Two ways to upgrade. First Install IDS11 in a new directory and point
rootdbs, loglogdbs and physlogdbs in the config file to the old chunks
and then start up. This is call an 'in place' upgrade. Has one or two
initial requirements (such as no outstanding 'in place alters'), but
is generally reliable, quick and simple. There is a back out procedure
that allows reverse conversion.
Second is to install IDS11, create a new config file and a new
instance on fresh disk and then unload/reload all your data. Takes
much longer but has the advantage of enabling new placement of data
and indexes, defragmenting the data and generally tidying the
instance. Your old instance is always available in the event of major
issues and this method is easier to test as it is non-destructive of
your data.
Look at the Migration Guide, this is why it was written !!
