DSPACE migration problems

[Jan Broulím]

Hello,

we are currently preparing migration from DSPACE 5 to 7.

So far we did the following

 - dump of the postgresql database, set the corresponding parameter db.url =...in local.cfg and grant user permissions

 - copy the assetstore and set the assetstore.dir=... parameter

However, when restarting the tomcat, dspace freezes and we get the following errors in the log:

 org.hibernate.tool.schema.spi.SchemaManagementException: Schema-validation: missing column [uuid] in table [public.bitstream]

 org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in file [/dspace/config/spring/api/core-hibernate.xml]: Invocation of init method failed; nested exception is org.hiber
 org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'authenticationRestController': Unsatisfied dependency expressed through field 'converter'; nested exception is org.springframework.be
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'converterService': Unsatisfied dependency expressed through field 'webSecurityExpressionEvaluator'; nested exception is org.springfra....
                   

Before migration, DSPACE was working corretly.

Any idea what we skipped?

Thanks

Jan
