Do I need to merge bai files also, while merging bam files

Question

[c_u]

I have 10 folders, each containing a bam file and a corresponding bai file. I need to merge the bam files, which I believe I can do with samtools merge merged_filename.bam *.bam.

My question is that do I need to also merge the corresponding bai files as well? And if so, should I just do - samtools merge merged_filename.bai *.bai?
