I am a technical guy. Could you explain further?Analysis of data to be migrated. We study the data that needs to be migrated. Understanding and documentation of the current Database Schema is a necessary.Identifying “complex architectural” components/ decision points. Necessary to ensure that the mapping later on is correct. Galleries/ digital assets mostly require specific treatment Srijan Technologies Pvt. Ltd.
I am a technical guy. Could you explain further? Intermediate Database Design • Poor implementation of old CMSs is a major challenge. • To handle the above situations an intermediate database schema has to be prepared. • Helps in a clean migration between existing CMS and Drupal, according to their own structures. Srijan Technologies Pvt. Ltd.
I am a technical guy. Could you explain further? Mapping current database to Drupal Schema. Srijan Technologies Pvt. Ltd.
I am a technical guy. Could you explain further? Defining a strategy for incremental migration. An “incremental migration” imports only the items which have been added or edited since the last time this migration ran. These items are identified by maintaining a "high-water mark" for each migration that comes from a primary key or date-time column on the source data. Migrate module automatically moves this high-water mark as content gets imported. Srijan Technologies Pvt. Ltd.
But I still have some concerns… $fileInsert = "insert into files Q. Can all digital assets be migrated?(uid,filemime,filename,filepath,status,timesta • Digital media in older CMSes and frameworksmp) are usually stored under separate folders withvalues (" . $uid .", " . $fileMime .", " . no correlations.$data[caption] . ", " . $filePath . $sourcePath. $data[name’] .", " . $status . ", " . $data[crdate] .")”; • For migrating the gallery images, small PHP snippets can be written to migrate digital assets.db_query($fileInsert);$fid = mysql_insert_id (); Check for some sample code here$galleryInsert = "insert into node_galleries(gid , nid, fid) values (" . $gid .", " . $nid . "," .$fid . ")";db_query($galleryInsert); Srijan Technologies Pvt. Ltd.
But I still have some concerns… Q. Can user information and the user relationships with pages, articles, blogs, galleries, be maintained? • Absolutely. Everything is covered under when the content is migrated. • All Articles/Pages/Blogs/Galleries are converted to nodes with different Content Types Srijan Technologies Pvt. Ltd.
But I still have some concerns…Q. Will there be downtime while switching over the website? Downtime cannot be avoided, but can certainly be minimized. “Incremental Migration” is used here to ensure that the site under development is kept up-to-date with the latest content. Especially useful when you are publishing articles daily! Srijan Technologies Pvt. Ltd.
But I still have some concerns… Q. I have a multi-lingual site. Can this be taken into account? • In most Multilingual sites, the DB has Latin1 charset tables. With UTF8 data stored. Such cases are handled by way of first converting the fields to BLOB, and then the BLOB field to UTF8. • Similar work done for http://knr.gl Conversion chart • Here is a more detailed account of the case http://www.srijan.in/blog/converting-latin1- charset-tables-utf8-data-set Srijan Technologies Pvt. Ltd.
But I still have some concerns… Q. I have a site with lots of data to be migrated. • Our work on IEP http://www.indiaenvironmentportal.org involved records exceeding 250,000. • The migration also involved cleanup of architecture to remove data redundancies, DataBase normalization, special characters cleanup and management of an extensive tag vocabulary.
