607 * The steps for the upgrader for after the new release is downloaded and |

608 * unzipped is: |
|
609 * 1. Test unzipped location for select files to ensure that unzipped worked. |
|
610 * 2. Create the .maintenance file in current WordPress base. |

|
612 * 4. Upgrade WordPress to new version. |

|
622 * 6, then you will not be able to access any portion of your site. Also, since |
|
623 * the upgrade will not continue where it left off, you will not be able to |
|
624 * automatically remove old files and remove the 'update_core' option. This |
|
625 * isn't that bad. |
|
626 * |
|
627 * If the copy of the new WordPress over the old fails, then the worse is that |
|
628 * the new WordPress directory will remain. |
|
629 * |
|
630 * If it is assumed that every file will be copied over, including plugins and |
|
631 * themes, then if you edit the default theme, you should rename it, so that |
