Importing project xpo in different environment

Hi,

I imported project xpo containing classes,tables,jobs,etc. in a different AX environment.

I'm getting index already used SQL Server error. for eg. the index 'I_106RecID' in table 'Table1' is already used before in 'Table2'

Is the metadata also copied in the process of export import AOT objects? 

Doesn't the new AX environment assigns fresh numbers from number sequences to the newly imported objects? If not, then how to export import AOT objects without worrying about metadata.

Thanks.
