The identifier 123/3 does not correspond to a valid Object in DSpace after Dspace database migration

[Ctil SD]

I'm migrating Dspace database from version 3.1 to 6.3 and during the process two scripts crashed when the flyway is running:

• V6.0_2016.04.04__DS-3086-OAI-Performance-fix.sql
• V6.0_2016.07.21__DS-2775.sql

After I fix the problem, the migration works fine.

The JSPUI appears with the names that I put in the local.cfg and shows my communities. But the link of community is wrong, for example:

• http://localhost:8080/jspui/handle/null

In Dspace v3.1, the link is 

• http://localhost:8080/jspui/handle/123/3

The link is repeated for all communities.

When I try to access a my communities with the correct link, the following message is displayed:

• http://localhost:8080/jspui/handle/123/3

The identifier 123/3 does not correspond to a valid Object in DSpace. This may be because of one of the following reasons:

The URL of the current page is incorrect - if you followed a link from outside of DSpace it may be mistyped or corrupt. You entered an invalid ID into a form - please try again. If you're having problems, or you expected the ID to work, feel free to contact the site administrators.

FYI, I have installed a new Dspace v6.3 with "ant fresh_install" and then performed "bin/dspace database migrate". Besides, for geolite database file, as the v3.1 is using geolitecity.dat while v6.3 is using GeoLite2-City.mmdb, I have downloaded GeoLite2-City.mmdb from internet and put in Dspace v6.3

Would you please advise how to solve?

Thanks!
