Re: [h2] Problem upgrading from h2 version 2.1.214 to 2.2.220
Noel, Andreas
I am Product Manager for 3 products all using H2 DB and backwards
compatability for updates is really an essential feature for us. All of
our products are onpremise deployments with marquee names in regulated
industries so this migration process your refer to is not ideal for us at
all. We allready ran through a migration process in a recent upgrade on
one of our products and it took Fredrik and team some time to get that
working efficientlly where it would not have an impact on key customers.
We update dependencies now with regularity to ensure maintenance and
security is efficient to having to run this migration process for each
product for each version upgrade is not what we want. Is there a plan to
make H2 DB updates backward compatible so we can just bump versions without
migration scripts having to be implemented?

Re: [h2] Problem upgrading from h2 version 2.1.214 to 2.2.220
Greetings.
You will need to Export to SQL Script and Create new DB from SQL
Script.
I wrote an UI that can help you with
that: https://manticore-projects.com/H2MigrationTool/index.html
There is an online version for testing small
databases: http://h2migrationtool.manticore-projects.com/
Cheers

Re: [h2] Problem upgrading from h2 version 2.1.214 to 2.2.220
You are going to need to do a dump/restore for this upgrade. Elsewhere on this group someone posted a link to a different tool that they wrote that helps with migration - that might be useful. I just normally code up some batch/shell files and run the backup and restore tools. -- You received this message because you are subscribed to the Google Groups "H2 Database" group.

[h2] Problem upgrading from h2 version 2.1.214 to 2.2.220
When we have upgraded the h2 library we get following error trying to open
the existing databases:
*Unsupported database file version or invalid file header in file
"/path/to/database.h2.mv.db" [90048-220] 90048/90048*
We use a file based database ("jdbc:h2:file:...")
Creating new databases works well.
Has something changed so the files are not compatible?
Any way to get around this in an easy way? The upgrade from version 1 was a
hassle for us earlier and we really wish not to do that again.
Is there any way to get more information about why it gets this error?
