Upgrading ownCloud to New Version Releases (view source)
Revision as of 19:46, 15 November 2016
, 19:46, 15 November 2016→Upgrading ownCloud 8.2.1 to Nextcloud 10.x on Amahi
Starting from the ownCloud 8.0 release, new releases are issued in a "time based" schedule. Please be aware due to testing and software changes a schedule can be changed suddenly.
===Upgrading ownCloud/Nextcloud on Amahi===
Use the following steps for upgrading ownCloud:
* It is '''highly''' desirable that your current ownCloud instance is at the latest release number (nothing below release 8.0.0 will upgrade) before the next major version release. This is important as there may have been some important meta data fixes (or other fixes) that the new major release is dependent on. If you skip this step the upgrade for ownCloud may have some problems at a future time. The following sub-steps use an upgrade from ownCloud 8.0.7 to 8.1.1 as an example.
===Upgrading ownCloud 8.2.1 to Nextcloud 10.x on Amahi===
About June 1, 2016 one of the founders, some developers, and some staff broke away from the ownCloud organization. The result was the creation of a "fork" product based on ownCloud 9, called "Nextcloud". Nextcloud 9 was introduced as a "plug-in" replacement for ownCloud 9. However, due to severe bugs inherited from ownCloud the update/upgrade process did not function correctly. Later releases of Nextcloud 9.0.54 and 10.0.1 repaired the process. Unfortunately due to the broken process many Amahi users are still using earlier stable releases of ownCloud. Implementing Nextcloud would have resulted in users starting from scratch with new installations. This is a problem for instances that have big collections of stored data and sharing configurations. Amahi has decided to go straight to Nextcloud 10.0.1. So the question, can we skip a major upgrade step (Nextcloud 9.0.54)? Well, kind of, with some issues, it is possible. This section will help you with that.
The '''NOTE: supported upgrade path''' should be for example; ''ownCloud 8.2.1 => Nextcloud 9.0.54 => Nextcloud 10.0.1''. This works flawlessly. The section steps that follow are not '''not guaranteed''' to work for Backup and Recovery every new upgrade instance of Nextcloud 10. ownCloud/8.2.1 is the earliest release tested. If the upgrade steps do not work for a new upgrade instance you will have to start with a complete new installation. The Nextcloud has been updated, please read carefully!Community will not help with issues where an upgrade step was skipped.
# Backup the ownCloud 8.2.1 (not guaranteed to work for anything earlier) instance to be upgrade, including the database.# Rename the old owncloud code directory in “/var/www/html/”, to say “xowncloud”.# Download and extract “Nextcloud 10.0.x” to a "Downloads" or other known location.# Rename the “nextcloud” binaries directory to “owncloud”.# Copy the downloaded binaries (owncloud) directory over to the "/var/www/html/" location.# Go to the copied "owncloud" directory under /var/www/html/, find PHP files; "version.php" and "index.php". '''Copy''' them to a known location, they will be required downstream in the upgrade.# In “owncloud” directory, in the “version.php” file.# Find the line containing "$OC_VersionCanBeUpgradedFrom".# Change the entry to: $OC_VersionCanBeUpgradedFrom = array(8,2,1); '''<span style="color:#FF0000"><== DO NOT TRY THIS FOR VERSIONS PRIOR TO V8.2.1, IT MOST LIKELY WILL FAIL.</span>'''# Drop and create the database instance.# Perform the usual recommended upgrade steps (from backups??): ## Restore the old "config.php". ## Restore the database. ## Set permissions and ownership to binaries directory structure.# Now do the usual upgrade process (i.e. via the browser GUI). The upgrade "should" complete successfully. '''DO NOT''' login to Nextcloud yet.# Copy the original “index.php” and “version.php” files from the "known" location in to the “owncloud” directory, replacing the existing copies (this will overwrite the modified version.php).# After the copying of the PHP files, restart the Apache or reboot the server.# Login to Nextcloud as the “administration user” and go to the “Admin” application. A scanning operation will begin in the “Security & setup warnings” section. # After a period of time a warning message will appear in “red” stating that a “Code Integrity check...” failure has occurred.# On the red line for this failure, "click" on the "Rescan" link. This will force a new Nextcloud scan. After the new scan the code check failure should disappear.# Test the new instance. On the surface most things will upgrade correctly. ::*Sharing and data configurations tested worked "mostly".::*Some applications may not upgrade correctly, usually disabling/enabling each application should fix the issue. ::*If using “External Storage Support”, there maybe a double entry for the same items. Delete the second one.<br/>
