Trying again migrating/upgrading a drupal 7 site to backdrop.

Followed the instructions, but running update.php I get following errors:

Error

Warning message

The staging configuration directory (./files/config_18424bb2b506807e530d9584de0e8c9e/staging) could not be found. Please make sure it exists and is properly referenced in settings.php.

Error message

PDOException: SQLSTATE[42S02]: Base table or view not found: 1146 Table 'buddhistisk_xd7.system' doesn't exist: SELECT name, schema_version FROM {system} WHERE type = :type; Array ( [:type] => module ) in backdrop_get_installed_schema_version() (line 170 of /home/buddhistisk/d7.buddhistisksamfund.dk/core/includes/install.inc).

SQLSTATE[42S02]: Base table or view not found: 1146 Table 'buddhistisk_xd7.system' doesn't exist: SELECT name, schema_version FROM {system} WHERE type = :type; Array ( [:type] => module )

The first one I don't understand.
The second is simply wrong. The db exist and is set up properly in 'settings.php' - and I did not write '.system' in the name.

Any help in here?

Even though you are talking about "migration" it seems to me that you are using an existing Drupal 7 database and try to run an upgrade? (I'm unclear on why you were trying to import users if you already had a Drupal 7 site which presumably already had the users in the database). There's a crucial difference - an upgrade can appear to be messier at first. And that can be off-putting.

If that is true, then I think you're not far off from having a functioning upgrade. When I'm at the stage where I've got Backdrop code but a Drupal 7 database, I will usually see a bunch of errors. But when I go to https://MYSITE.site/upgrade.php it'll show that there are a lot of upgrades to be done to the tables. So far so good. I attempt to run them all. And it might go well. After that I can log in and go to Configuration > File System so it can find the new file directory. And it'll seem more or less working.

Some times it takes a few tries and tweaks.

I always make sure all my modules were updated to the latest versions on the Drupal 7 site before starting. I make sure that I've removed any modules I don't need on the Drupal 7 site. And make sure all the modules have an upgrade path and are present when I'm trying to do the final upgrade.

Update:

The first error disappeared on second try. But - - :

Error

Error message

As said above, I have not put in '.system'. Where does that come from & how do I eliminate?

Here is the line from setup.php:

$database = 'mysql://buddhistisk_xd7:password@localhost/buddhistisk_xd7';

password of course changed. User & db have same name.

Are you pointing the settings file at the “Backdrop ready” database, or an empty database?

Should be backdrop ready. Set up on same account as backdrop. Empty db with imported data from D7 db

If you look in that database, does the `system` table exist?

Just spitballing: Egmund, can you check if your database password contains special characters like a forward slash, a semicolon, or a hash sign? They can cause issues in certain cases.

Hi Olaf,

No just several % and an @ plus three .

Okay! I'm not sure if my list of special characters is complete, but I think, the ones mentioned by you shouldn't be an issue. (To be sure, you could still try with a a password of only numbers and letters.)

No more ideas, at the moment.

Not going to. It would be really bad code if normally accepted passwords would not function here.

Well, tried anyway. Now I get:

Error

Error message

PDOException: SQLSTATE[HY000] [1045] Access denied for user 'buddhistisk_xd7'@'localhost' (using password: YES) in backdrop_get_installed_schema_version() (line 170 of /home/buddhistisk/d7.buddhistisksamfund.dk/core/includes/install.inc).

SQLSTATE[HY000] [1045] Access denied for user 'buddhistisk_xd7'@'localhost' (using password: YES)

Why would that be denied? User exist and have all rights to the db.

Well. Seems connect line in settings.php should not contain @localhost.

The above error disappeared. Now I 'simply get a blank page running update.php

Error in server log:

[04-Oct-2021 14:11:59 Europe/Copenhagen] PHP Fatal error:  The database setting could not be parsed. Please check the $database setting in settings.php. in /home/buddhistisk/d7.buddhistisksamfund.dk/core/includes/bootstrap.inc on line 841

Apparently several wrong info in 'how to install'

Here the string (slightly altered pw):

$database = 'mysql://buddhistisk_xd7:olga25FTE21/buddhistisk_xd7';

Again spitballing (I haven't run into the issues you are facing) but could you try using `@127.0.0.1` instead of `@localhost`?

That gives me:

Error

Error message

PDOException: SQLSTATE[42S02]: Base table or view not found: 1146 Table 'buddhistisk_xd7.system' doesn't exist: SELECT name, schema_version FROM {system} WHERE type = :type; Array ( [:type] => module ) in backdrop_get_installed_schema_version() (line 170 of /home/buddhistisk/d7.buddhistisksamfund.dk/core/includes/install.inc).

SQLSTATE[42S02]: Base table or view not found: 1146 Table 'buddhistisk_xd7.system' doesn't exist: SELECT name, schema_version FROM {system} WHERE type = :type; Array ( [:type] => module )

Which I 'escaped' by eliminating @localhost (this site is on a shared server). See above post.

I got this hint from another experimental site - a fresh install, where I tried to 'import users' (as you know).

In the meantime I tried 'user-import' into a MODX site - worked without any errors (except my own typing errors). Besides I asked in MODX forum about another problem with a MODX module - got answer within minutes, that were actually useful. No, I am not putting your efforts to help down - there is just a huge difference in quality of code as I see it between these two CMS systems. I wanted to try backdrop one final time - gave up a couple of years ago - because of my knowledge and use of Drupal 7.

Edit:

Sorry, you are right. The @127.0.0.1 was in the other site's connect-line. Any way  -- didn't work (as you see in the error msg).

& where does this '.system' come from?

By the way: The 'system' table exist but as 'drup_system'

Ah. That's important information. In your settings.php do you have any value set for the database prefix?

$database_prefix = '';

I think that should be in your case:

$database_prefix = 'drup';

I don't generally use prefixes so I'm not 100% sure -- it's also possible it should be:

$database_prefix = 'drup_';

Drupal usually set prefix as 'drup_' .

I tried to remove it from 'system' table, but didn't change the error.

I am not suggesting to start changing table names one at a time, but adding the database prefix that you have used in this database into the Backdrop settings.php file so that it knows the tables are prefixed.

I put in the 'drup_' ans something happened: I am getting an awful lot of errors (after ignoring a couple):

Seems I need to disable or uninstall a lot of modules.

& now I'm retiring for the day.

Thank you Laryn for taking the time to help me - & I apologize for overlooking the (problem with) the prefix (should maybe be clearer in the migrate instructions).

The errors I get now are too overwhelming for me to deal with. I give up on backdrop. I have a functioning backdrop site, but could not even import users, the most important thing, into it. The so-called 'built-in' path for D7 is definitely worse than Drupal's own D7 to D8/9 migration 'feature'.

Thanks for letting me know. It's too bad the oversight about the prefix used up so much of your troubleshooting energy -- but come back any time if you would like to try again.

I'll keep the issue you filed in User Import open and try to do some testing when I get a chance. Thanks for reporting.

EDIT: Just noting that:

  • another avenue for importing users might be the Feeds module which also has a CSV import option and can be directed to import Users instead of Nodes
  • I've made a new release of User Import

Thank you Herb for trying to help.

I had two sub-domains for experimenting. One w. D7 database and backdrop code. The other a fresh install of backdrop where I tried to import users.

These sites are now eliminated since neither update nor user-import worked.

I tried the update path a couple of years ago on another domain - catastrophic result. I therefore upgraded D7 to D8 (easy) and later converted to MODX (also easy).

I see some people have much better luck w. backdrop, but to become more popular there has to be a simpler/easier way to 'convert' from D7 to backdrop.

Maybe I am getting too old/senile.
