Update from 5.6 to 5.7/8 with migration_tool
i have a running installation of version 220.127.116.11 which i want to upgrade. I used the migration_tool in order to export my data. Then i installed a clean system in order to import the data. Both with 5.7 and 8.1 the migration_tool could not be installed with error message: "This package requires concrete5 version 8.2.0a1 or greater."
I am lost... i hope anyone can help me. :)
I'm including the whole process here for anyone else that might run into this problem - you already said you have 18.104.22.168 installed.
There are two versions at http://concrete5.org/download that you want.
First you want to upgrade your legacy (after clear cache & database backup) to 22.214.171.124 - very bottom of the download page.
Then a fresh install of 8.2.0RC2 (greater than 8.2.0a1) - second link on the download page. Of course waiting for 8.2.0 full release should also work.
Then grab the lastest packages from GitHub:
https://github.com/concrete5/addon_migration_tool_legacy... for 126.96.36.199
https://github.com/concrete5/addon_migration_tool... for 8.2.0RC2
Much work has gone into the migrations specifically for these versions.
Keep us posted on your progress - John
