Will there be any impact if we migrate HP QC projects from EST timezone to UTC timezone?

Hi ,

Will there be any impact if we migrate HP QC 11.52 projects from an Infrastructure having EST time zone to another Infrastructure of same HP QC 11.52 version having UTC timezone?

Here below 2 approaches are considered for projects migration:

1. If project size is < 4 GB , export from EST infra, in form of QCP file and import into UTC Infra in the form the QCP.

2.If project size is > 4 GB, bring in seperately database and repository from EST infra , copy them to UTC Infra and restore the project.

Please advise on whether there will be any impact because of this time zone change?

What are all the scenarios I have to consider before proceeding with this time zone change, is it recommended?
