There's HOWTOs on doing this. You won't use all the features, but your
files will convert to extents while being updated.

To be safe, reinstall your bootloader after converting.

Thanks for telling me to look at "entry 5" but not enumerating the
entries. Thanks for quoting 10 year old information without giving a source.

What are you trying to tell us again?

Ext2

Ext2 stands for second extended file system.
It was introduced in 1993. Developed by Rémy Card.
This was developed to overcome the limitation of the original ext file
system.
Ext2 does not have journaling feature.
On flash drives, usb drives, ext2 is recommended, as it doesn’t need to
do the over head of journaling.
Maximum individual file size can be from 16 GB to 2 TB
Overall ext2 file system size can be from 2 TB to 32 TB

Have a look at entry 5.

I gave you credit to be able to count, I guess you have trouble with that.

It is not 10 year old information it was published just after ext4 came out

google is your friend.

But there is no ext{2,3} these days. The driver is ext4 for all ext* FS, only
configurations differ...

It is still outdated information. After ext4 came out, it took a few
months until Google started implementing ext4 without a journal -
precisely because ext2 was outdated and had bad performance. This work
has been finished long ago and is available to everyone.

It seems Google is _your_ friend.

Is the information on the move from ext3 to ext4 valid for the issue at
hand?
