Accounts & rollen
Taxonomieën
Bestanden: Gebruiker-afbeeldingen en overige bestanden
Nodes van het type: Afbeeldingen, producten, stories, webformulieren, en vermoedelijk nog meer

Wat deze module niet kan migreren: Orders.

Installatie

Je moet de module installeren op de Drupal 7-doelsite
Installatie: drush en -y migrate_d2d, migrate_d2d_ui

Gebruikersinterface

Je vindt de interface via:

Migratie bestanden

migrate_d2d kan oa. bestanden migreren. Dat loopt niet geheel foutloos, maar voor mij belangrijker: Die bestanden staan los van eventuele node waar ze bij horen. Dat maakt de losse migratie van bestanden vrij zinloos. Hetzelfde geldt voor handmatig kopiëren-en-plakken: De crux zit 'm in de associatie van bestanden (productafbeeldingen in dit geval) met overige objecten.

Specificatie van het bronpad is een beetje vreemd, want /files/ lijk je te moeten weglaten uit de padnaam

Vreemde foutmelding omtrent een leeg argument voor copy(). Misschien worden spaties in bestandsnamen niet escaped?

Bestanden belanden in de map /var/www.../files/files. Is dat geen vergissing?

Nog interessanter: Migreert deze module domweg alle bestanden, of alleen de bestanden die daadwerkelijk gebruikt worden? Ik heb de indruk dat-ie alleen gebruikte bestanden overfietst, en da's verrekte handig! Aansluitend met kopiëren en plakken alle bestanden teruggezet van files/files/ naar /files/.

Casus feb. 2016: 11.000 accounts importeren

In februari 2016 heb ik moeiteloos 11.414 accounts geïmporteerd:

Alleen accounts geïmporteerd: Overige objecten (waaronder rollen en profielfoto's) waren niet relevant, en gaven in het verleden complicaties
Pas na een paar minuten verscheen er enige informatie omtrent voortgang. Geduld is een schone zaak
Tijdsduur complete migratie: Ca. een uur.

Casus mrt. 2016

Step 4: Files: Niet vergeten om het pad mee te geven, bv. /var/www/example/com/sites/default/files/
