Migrating from Magento 1.9.4 to Magento 2.4.1 – use the The Magento Migration Tool OR do it manually?

Magento 1.9.4 to Magento 2.4.1

We need to migrate from the older version of Magento to the newest. My plan was going to be to:

  1. Install Magento 2.4.1
  2. Export Customers, Products and Orders via CSV files from the old Magento, correct the column headings and import into new Magento.
  3. Configure themes

Now I came across this ‘Magento Migration Tool’ and I wonder if it’s better to go this route? Would I need to set up the websites/stores/storefronts/categories or anything or does the Migration tool does all?

I am currently getting some Error messages in the process of trying to install the Migration tool but my hosting is looking into that. After that is resolved and I’m ready to use the tool, is it just a matter of typing the command into SSH (Putty) and waiting for the process to complete? How long are we talking? Obviously, that would depend on the size of the database but what is the average for a small store? Also, will there be other bits and pieces I would still need to do manually afterwards?

media library – Does using the WordPress Import tool still include attachment data if “Download and import file attachments” is not selected?

I’m in a unique situation where I have to import WordPress content into a production server, but I don’t have SSH access to the server files or database. I can’t install plugins on the production server, so I am limited to the built-in WordPress Importer tool.

I don’t have any issues bringing over Posts and Pages, but it’s extremely hit or miss when bringing over the Media Library, of which I have something like ~2000 items.

What I do have, however, is access to the S3 bucket where the production server hosts the Media Library. The production server also automatically rewrites URLs for the media library to point to the S3 bucket.

My question is: If I migrate my Media Library files to my S3 bucket beforehand, then use the WP Exporter tool to export “All content” from my source site and import it into my production site and leaving “Download and import file attachments” unchecked, will my Attachment data (not the files themselves) still be imported into the database?

data structures – Given an abstract argumentation framework, is there a tool that can compute: conflict free, admissible and all extensions?

I am trying to find an online/offline tool that can compute the following:

Given an abstract argumentation framework <S, R>, where S = {a1, a2, a3, a4, a5} and the attack relation
R = {(a1, a2),(a2, a1),(a2, a3),(a3, a4),(a4, a5),(a5, a3)}. What are the:

  • Conflict free subsets (In this case: {}, {a1}, {a2}, {a3}, {a4}, {a5}, {a1, a3}, {a1, a4}, {a1, a5}, {a2, a4}, {a2, a5})
  • Admissible subsets (In this case: {}, {a1}, {a2}, {a2, a4})
  • Complete extensions (In this case: {}, {a1}, {a2, a4})
  • Grounded extensions (In this case: {})
  • Preferred extensions (In this case: {a1}, {a2, a4})
  • Stable extensions (In this case: {a2, a4})

As long as the S is 6 or less, it is reasonable to compute this on paper. But as soon as we get something like an S of size 10, we suddenly need to start computing 2^10=1024 different subsets. So I was wondering, is there some online/offline tool/platform/program that can compute this. As my S can be no larger than 10, efficiency is not a big issue here.

model checking – Is there a tool that can check whether m |= p holds, where m and p are both ltl formula

Yes, you can use an LTL-to-Buchi-automaton translator for this.

Let’s assume that you want to check if $psi rightarrow psi’$ is a valid LTL formula, i.e., every word satisfying the LTL property $psi$ also satisfies the LTL property $psi’$. This case is equivalent to finding out if $psi wedge neg psi’$ is satisfiable. Your $psi models psi’$ notation is another way of writing this, but I would avoid it since the $models$ relation is often defined differently in current research papers on the topic.

If we translate $psi wedge neg psi’$ to a Buchi automaton, we can easily check if its language is empty. In fact, optimizing LTL-to-Buchi translators remove states with an empty language, and hence you only need to check if the resulting automaton has no accepting state.

On example LTL-to-Buchi translator is ltl3ba. For instance, if you want to check if $mathsf{F G },a$ implies $mathsf{G F},a$, you can do that as follows:

./ltl3ba -f "(F G a) && !(G F a)"

Here, “-f” stands for “translate this formula that is given as a parameter”.

The result is given in SPIN never claim form:

never {    /* (F G a) && !(G F a) */

There is no state ending with “_accept” in the name, which means in the SPIN never claim notation that there is no accepting state. So $(mathsf{F G },a) wedge neg (mathsf{G F},a)$ is not satisfiable.

There is also at least one LTL-to-Buchi translator with a web interface, namely the one from the SPOT framework.

Does anyone use the ‘whos.amung.us’ tool? Help

Hello everyone!

If you are not familiar to the ‘whos.amung.us’ tool, it tracks in real time how many users are on your website. Anyways, I have been using this for MONTHS. Now all of the sudden, I have received several e-mails from AVG Anti-Virus users saying AVG picked up a threat coming from this tool. I have removed this tool, and since then, there have been no virus threats. Has anyone else been experiencing this?

If anyone has AVG (I use avast), can you check out my second site (www.savespark.com) and tell me if a ‘virus threat’ comes up? I have not removed the ‘whos.amung.us’ tool from my second site. If no virus threat comes up, I want to put the code back onto my main site
