DB copy- re-using online redo files of target database

Question

Hello again,
One question regarding DB copy from PRD to TST database (both are existing and running DBs). Can it cause problems when you don't remove online redolog files on TST database (e.g. log_g11m1.dbf...) during the copy ? Can those files be reused when stating 'alter database open resetlogs'? or could be any redolog files (even from totally other database) be reused - with same size, of course.
If you don't delete it , can it cause an error ORA-00305: log 4 of thread 1 inconsistent; belongs to another database ?
I am bit wondering, because I don't see any reuse in control trace file:
LOGFILE
GROUP 1 (
'/oracle/XXX/origlogA/log_g11m1.dbf',
'/oracle/XXX/mirrlogA/log_g11m2.dbf'
) SIZE 250M,
GROUP 2 (
'/oracle/XXX/origlogB/log_g12m1.dbf',
'/oracle/XXX/mirrlogB/log_g12m2.dbf'
) SIZE 250M,
GROUP 3 (
'/oracle/XXX/origlogA/log_g13m1.dbf',
'/oracle/XXX/mirrlogA/log_g13m2.dbf'
) SIZE 250M,
GROUP 4 (
'/oracle/XXX/origlogB/log_g14m1.dbf',
'/oracle/XXX/mirrlogB/log_g14m2.dbf'
) SIZE 250M
Thx a lot for explanations in advance!

Hello,
I dont want to share them. I just meant, I have TST database running and I want to replace it's content from PRD database. So I delete all datafiles and do restore. BUT I do not delete online redolog files, I keep the files . Can these files be reused once I restore datafiles from PRD to TST?
