1.2 | 1 | After having upgrade the XWiki instance to a recent version (7.4+), you should convert your existing pages to nested ones. This will permit: |
| |
1.3 | 2 | * (1) to keep the existing hierarchy between pages, made with the parent/child relationship, which will be lost otherwise. |
| 3 | * (2) give you the opportunity to create pages under any old page, as you could under new pages. | ||
| |
1.2 | 4 | |
| |
1.3 | 5 | To perform this conversion, we have developed an application called [[Nested Pages Migrator Application>>extensions:Extension.Nested Pages Migrator Application]]. Its principle is to move all existing pages under their parent, so that the old parent/child relationship become physically represented by the Nested Pages hierarchy. |

1.4 | 9 | However, the current hierarchy may be messy. For example, so pages inside the space ##Proposal## could have ##Main.WebHome## as parent instead of ##Proposal.WebHome## which would be more logical. It happens when the user is invited to create pages in the space ##Proposal## directly from the main page (ex: http://design.xwiki.org/). |

1.3 | 10 | |
| |
1.4 | 11 | It's important to identify such a case before applying the migration tool, because the tool won't be able to detect this kind of unwanted hierarchies. |
| 12 | |||
| 13 | In the previous example, the solution was to put manually the parent of all pages of the ##Proposal## space that had ##Main.WebHome## as parent, to ##Proposal.WebHome##. The following script have been used to migrate (ex: http://design.xwiki.org/): | ||
| 14 | |||
| 15 | {{code language="velocity"}} | ||
| |
2.1 | 16 | #set ($xwql = "where doc.space in ('Proposal', 'Design', 'Improvements') and doc.parent = 'Main.WebHome'") |
| 17 | #foreach($r in $services.query.xwql($xwql).execute()) | ||
| 18 | #set ($d = $xwiki.getDocument($r)) | ||
| 19 | #set ($discard = $d.setParent('Proposal.WebHome')) | ||
| 20 | #set ($discard = $d.save()) | ||
| 21 | * $r updated | ||
| 22 | #end | ||
