SharePoint online site redirect to new site

Hi Community,

I have created new site in SharePoint online say /sites/new/ and now i want to redirect all users visiting site /sites/old/ to the newly created site.

I know there are options to achieve it through Script editor web part and content editor web part. Is there any other way than what i mentioned above ?

Second, is there any way in SharePoint online through some OOB web part that will redirect users of specific AD or SPO group to specific site ? I figured there is a user redirect web part in on-premise but not sure about SPO.

Could someone please add detail to the asked questions ?

Regards,

Tayyab
