SharePoint 2007 to 2013 migration via DB attach method

[Sudesh Withanage]

To do this migration from 2007 to 2013 We are having intermediate 2010 environment in different domain.
Example:
2007 - ABC\user
2010 - TESTDomain\user
2013 - ABC\user

Will there be any issue with permissions in this situation after migration?

[#2]

Yes since the usersinfo table will still contain the same users in it after migration.

[#3]

Do you mean there will be or not issues ;-)? By the way: Do you think (Sudesh) you can elaborate more on what kind of permissions issues you are talking about?

[#4]

Requirement is to retain same permission in 2007 after migration to 2013. Since intermediate 2010 env is being in a test domain not sure if this can cause any issue.
