Inodes are unique in the borders of a single filesystem. Inode number is a pointer to the structure that is containing all the information that you mentioned. The number itself does not contain them. So changing file's info in the inode structure doesn't need to change the inode number (and it is not happening).

E.g.

So all the current file names are unique, so are the new file names.... (1 Reply)

xfs_ncheck
xfs_ncheck(8) System Manager's Manual xfs_ncheck(8)
NAME
xfs_ncheck - generate pathnames from i-numbers for XFS
SYNOPSIS
xfs_ncheck [ -i ino ] ... [ -f ] [ -s ] [ -l logdev ] device
DESCRIPTION
xfs_ncheck with no -i arguments generates an inode number and pathname list of all files on the given filesystem. Names of directory files
are followed by /.. The output is not sorted in any particular order. The filesystem to be examined is specified by the device argument,
which should be the disk or volume device for the filesystem. Filesystems stored in files can also be checked, using the -f flag.
OPTIONS
-f Specifies that the filesystem image to be processed is stored in a regular file at device (see the mkfs.xfs -d file option). This
might happen if an image copy of a filesystem has been made into an ordinary file.
-l logdev
Specifies the device where the filesystem's external log resides. Only for those filesystems which use an external log. See the
mkfs.xfs -l option, and refer to xfs(5) for a detailed description of the XFS log.
-s Limits the report to special files and files with setuserid mode. This option may be used to detect violations of security pol-
icy.
-i ino Limits the report to only those files whose inode numbers follow. May be given multiple times to select multiple inode numbers.
If the filesystem is seriously corrupted, or very busy and looks like it is corrupt, a message of the form that would be generated by
xfs_check(8) may appear.
xfs_ncheck is only useful with XFS filesystems.
