The Alfresco V2.1 upgrade doesn't deviate from the general upgrade process.

As of V2.1, the following occurs during a schema upgrade: Schema Upgrade Script Execution

The original intention (pre V2.1) was to have a failure cause rollback of all the attempted schema changes, but most databases don't support the rollback of schema changes. Some databases won't allow new tables to be visible in the same transaction that created them. So, if the server schema upgrade fails, the only viable option available is to find the cause of the issue and try again on a fresh database created from the backup.

There are no known bugs or workarounds associated with the schema modifications.
