By performing an upgrade, you can migrate (or convert) your existing ext2 file system to an ext3 file system. This operation preserves your existing files.
The advantage of migrating to ext3 is that you have journaling file system capabilities. The ext3 file system do not have to be fscked after an unexpected reboot, unlike the ext2 file system. This can drastically reduce the amount of time for the system to come back up and be ready to use.
Je preto odporúčané, aby ste si zvolili konverziu vašich súborových systémov.
To do so, select the partitions to migrate to ext3.
When you are done, click Next to move forward.
