I don't know of any way to rename an existing namespace. To delete a namespace:

namespace delete namespace_name

All the child namespaces, proc, vars within the namespace will be deleted as the result of this call.

Namespaces cannot be renamed. There's no operation to do so, and the implementation strongly assumes that it is impossible. – Donal Fellows Aug 28 '13 at 09:49

Use this proc to rename any given namespace:

proc renameNameSpace {oldNameSpace newNameSpace} {
    foreach proc [info procs ::${oldNameSpace}::*] {
        rename $proc ::${newNameSpace}::[lindex [split $proc ::] end]
    }
}

Maybe this approach offers a solution. Where ns1 is the source namespace, and ns2 the destination.

proc xxxx {ns1 ns2}  {
    namespace eval ::${ns2} {}
    set map [list $ns1 $ns2]
    
    foreach type {commands vars procs } {
        foreach item [info $type ${ns1}::*] {
            set err ""
            catch { rename $item [string map $map $item] } err
            if { $err != "" } { puts $err }
        }
    }
namespace delete $ns1
}
