Framing the issueΠέμπτη, 31 Μαρτίου 2011

Site transfers are easy, but… Transferring a site replaces an existing oneΠέμπτη, 31 Μαρτίου 2011

Why is that a problem? Live site and dev site start as identical twins You redesign the dev site = changes The live site is ever changing = even more changes The two sites have now ﬂoated too far apart How do you combine two sites into one site without data loss?Πέμπτη, 31 Μαρτίου 2011

Ever changing live sites?! New or updated users Forum posts Comments Sales Any other kind of user submitted informationΠέμπτη, 31 Μαρτίου 2011

To the rescue!Πέμπτη, 31 Μαρτίου 2011

A man with a plan 1.Identify changing data 2.Exclude them from the dev site backup 3.Merge the two sitesΠέμπτη, 31 Μαρτίου 2011

Excluding users’ tables • Joomla! 1.5 • Joomla! 1.6 ➡ #__users ➡ #__users ➡ #__core_acl_aro ➡ #__user_usergroup_ ➡ #__core_acl_groups_ map aro_map ➡ #__user_proﬁles Don’t forget user mapping tables from other components! (forum, K2, download system, ...)Πέμπτη, 31 Μαρτίου 2011

Excluding tables • Not an exact science. Be patient and careful! • Tables are usually named like jos_component_table, e.g. jos_k2_items • Exclude tables which have changed on the live site • If unsure, ask the component’s author • You can’t merge two versions of the same table • Use Database Table Exclusion to exclude themΠέμπτη, 31 Μαρτίου 2011

Database table exclusion Example: Excluding K2’s items from the backupΠέμπτη, 31 Μαρτίου 2011

Excluding ﬁles and folders • No need to exclude extensions • Good candidates for consideration: ✓ Avatars (JomSocial, Community Builder) ✓ E-shop product images (VirtueMart, Tienda, redShop) ✓ Forum attachments (NinjaBoard, Kunena, Agora) ✓ Downloads (ARS, DOCman, RokDownloads) • If unsure, ask the component’s developer • Use “Files and Directories Exclusion” to exclude themΠέμπτη, 31 Μαρτίου 2011

Things to never do • Skip the contents of the table instead of excluding it • Use the “Extensions Filter” feature • Have users add/modify articles on the live site while you modify the same or different articles on the dev site. • Take separate database and ﬁle backupsΠέμπτη, 31 Μαρτίου 2011

Test merge • Backup the live site and restore locally to a test site. • Backup the dev site and restore on top of the test site. • Check the new site ‣ Missing users ‣ Logging in as a user created just before the test merge ‣ Scrutinized review of your site’s features ‣ Also try creating users, posts, test sales, etc. • Is everything working? If not, review your exclusions!Πέμπτη, 31 Μαρτίου 2011

Live merge • Backup the live site and keep a local copy! • Put your live and dev sites off-line. • Backup the dev site. • Uninstall extensions from the live site that were uninstalled on the dev site. • Restore the dev site backup on top of the live site. • Check that everything works. If not, restore from backup. • Put the live site on-line.Πέμπτη, 31 Μαρτίου 2011
