ID 461609 - Migration Script will not reuse a migrated sequence

Problem summary
Migration Script will not reuse a migrated sequence

Customer reported version
flix_6.3.5

Customer reported platform
centos7

Steps to reproduce

1) Create a sequence in Flix 5 with a title longer than 10 characters and no tracking code

2) Migrate it once to Flix 6

3) Migrate it again

Expected behaviour

The 2nd migration should reuse the sequence which the first migration created

Actual behaviour

A new sequence is created because the tracking code of the sequence in Flix 6 is using the first 10 characters of the title of the sequence in Flix 5. When the migration script runs a second time it checks if the sequence already exists in Flix 6, but because the characters after the 10th are cut out in the Flix 6 tracking field, it doesn't match and it creates a new sequence. The Title in the Flix 6 sequence is correct and if checked against it, it should work.

Workaround

Create a tracking code for the sequence in Flix 5
